I live in the Colorado mountains and I have NO power with a carb (Dick Paterson rebuild). If I had the $$ I'd go with a TBI.

Bill, I question your thinking. I do not think you will get any more power out of a TBI system vs. a carb. I believe your problem is lack of air (air density). Delivering a little more (or less) gasoline to the air fuel mix should not make much difference or you power. What I believe you need is more air.
That said, I do not have a TBI or port injection on my GMC so I have no real world GMC experience to fall back on to proove my thinking.
I do have several thousand hours of flying experience various altitudes to back up my thinking. When we want more power in a gasoline airplane at altitude we add more air (turbocharging).

Have not been following this thread, not had time to get up on the net much lately but since it looks like many are putting 2 cent in on this I figured hey, I might be able to shed some light on the subject from this side of the bench.
it really comes down to what you are looking for out of your GMC. if it is a object of your frustration, something to keep you out of the bars and into the realm of a custom hot rod for your fingers only then TBI or direct port is probably for you. I have been to this mountian, fell off the other side so to speak and am here to tell the tale. I build coaches mostly for folks to use not to play with and for that guy-- someone who does not feel the deep seated desire to mess with their machine and make allowances for it time and again, a carb is the way to go. i know this throws in the face of what many will tell you is an atribute of FI, I tell you now-- for installing an aftermarket FI system on an old war horse motor you are crawling down the wrong hole.
This is where I get dander up-- and i know there are many out there that are pleased as punch with their FI systems but before you string up my ideas please tyake a listen and this is for those out there sitting, thinking about making the plunge-- I just want you to have a full view of what you will be getting into.
One of the huge positives about owning and maintaining a GMC is that it can be looked at as a "pregnant Toronado". It is really simple to work on, get fixed, find parts for and have someone work on. Bubby over there on that tractor had his daddy cut his teeth of keeping his Toro on the road and when a stock 455 breaks down there are many people out there qualified to work on it. there were fifty million Q-jet carbs made and just as many parts made to fix them and people out there who know what to do to fix them. Complicate the world by throwing in an aftermarket FI system on top of it all and your pool of techs start to dwindel.
Couple that with the absolute fact that if you do have issues you, yourself will have to be an integral part of the diagnostic tree, the identification and procurment and many times the installation of the unique parts that make the system work. Make sure you are happy to do that-- and many people are-- before you get involved in any form of FI.
Now it's true all new cars have FI as well as total engine management designed computer systems and it is true these systems are very reliable but look, that is not what you have. The auto manufacturers spend millions of dollars tayloring those systems to the drive train-- we are only adapting one system at a time. There is no way you can link together the system you purchase in a box so seemlessly to your old 455 or 403. You have to sort of wing it in and together. Some systems seem to work well and of course that is the goal but not only is there no guarantee but chances are there will be time and energy put into adapting any FI system that was not anticipated. When I work on a coach, folks want to know how much it will cost to do whatever it is we will do. it is difficult to leave a project open ended and that is exactly what you have to do installing a FI system. You never know what road block you will run into. I have installed
enough FI systems, repaired them and got coaches going that had them to know they are like a box of chocolates. One person says I got a cherry while another one finds they have a pit!
What is the goal--- do you want appreciably more mileage, more torque-- you will not get that from the bucks put into a FI system. Do you want a faster, smoother start up and no dieseling when it turns off-- that is possible. Do you want altitude changes to the timing of the motor, OK you can usually get that but hey, it will not effect performance enough to make the move cost effective and that is what my customers seek. Does it make the motor easier to get fixed-- no, usually you will have to do the job and if not there will be a charge for the tech to understand what is there before they can work-- that costs $. Is it cheaper to work on-- no -- so what is the reason to do it? To be cool, OK, I'll give you that but must of my customers just want the motorhome to run reliably and you can get that with a good running, maintained carberator. Yes, you might have a shorter maintenance cycle before you need to have work done but doing it yeilds a
good running machine almost every time. Sorry but as I said after climbing the mountain and about having folks upset at me I have to say a carb will do for a GMC all that is expected and it will keep the machine in the realm of reliability and easy of maintenance most look for if they seek a usable coach.
I will not install a FI system, there are other shops that will and if you say-- hey, I still want one of those please seek out those that like and will install and back a FI system, I am not warm and fuzzy abot that leap for mankind anymore. I have to customer who blew off their direct port FI systems and now have a coach that runds, gets descent mileage and can use it without fear. Thats enough proof for me.
Some will say, awe-- he doesn;t know how to properly install a FI system-- sorry but nope, thats not the case. I can install it just fine-- the problem comes in setting up and maintaining the machine of which I -- the installer -- is not responsible for. Bottom line, if you want to link your personal abilities and labor to yur coach. If you wanna be the one to keep her running and you like to have someing different then by all means go for a systemm. I think you might have fun with it but if you want your coach to run now, tomorrow and the future with a minimum of grease under your own fingers-- brother stick with your Q-jet.
Now I know there are many contrasting views and I welcome them to make their proposal to all who want to dive into that deep end of the pool, just know I'll be at the shallow end with a towel.
My opinion--- Jim Bounds

Thanks Jim for writing this up. I'm one of the guys debating this issue. I have a Quad and have had it rebuilt, and have no troubles with it on how it responds. I'm in Missouri and it serves me well, but I would like to use the coach in the mountains. What would be nice is to know how to adjust the distibutor for the timing and also the carb to run it's best in the mountains. If I could get that information then I'll try to adjust it when it's time to go through the mountains. Is that a reasonable approach?

If you have not yet, Please read. . .
Jim, Come on guy - Tell us how you feel.. 
I will confirm everything that Jim has said, but I think he has possibly understated the case!
Let me start by saying that in my years to doing engine stuff for four American (there used to be) and three import manufactures, I did four refits to electronic fuel injection and five turbo-charger additions to existing engine families.
I will tell you right up front that this is not something you want to mess with to save money or improve horsepower. If you doubt that, open a spread sheet and calculate how many miles it will take to recover the cost of the modification. (Hint: If you can get an increase from 8 to 9 MPG, it will only take ~30,000 miles to break even for Each 1k$ invested.)
If you are not already a very serious gear head with technical aptitude for computers and mechanical gadgets, this is something you should approach with great caution. Even if buy a used coach that is reported to "start and run great".
Several have said that they would like altitude correction. That is a very different issue. As any pilot can tell you, adjusting the mixture (as a computer managed engine should do) will help, but it will not solve your problem. As is said in the business, "Air is Horsepower". (Fact) If you live and drive at at 9000msl, you are SOL.
There are cures, but none are inexpensive and simple.

As the person who kicked off the latest round of this discussion - thanks so much for all those contributions. Jim B, I take your point about the simplicity of a carb over a fuel injection system. When all is said and done I guess a carb is more fixable on the side of the road. I would be interested in hearing from more GMC owners with TBI - what's been your experience? How reliable are the systems out there?
George mentioned that California will demand you re-instate a carb on a post '75 vehicle - and that's very useful as this coach may well end up in California. Is this a flat-out rule for CA or does it depend on the inspector?
Jim G, you asked who would do the tuning; that's a good point too, and unresolved... Also, great advice from everyone to look for the coach with the right spec, and worry about TBI/carbs later.
Here's the thing. I am English but live/work in Washington DC. My job here expires in June but I found out this morning that I am going to be staying in the US through next year - either in California or Boston, with a new position which starts in September. So my plan is to buy a GMC and spend the summer driving to whichever destination we end up at (I have a wife and son). We'd keep it for weekends and probably at least one other big trip before we go back to the UK. We've done some big RV trips before so we know what we are in for and we've had a look around some GMCs too.
So, here's my wish list...
We are looking for a 26' coach which is ready for a big roadtrip. I am handy enough but have neither the time nor space right now to do a whole lot to it.
I need either a fixed double bed in the back or seating that converts to a double, and the sofa/bunk up front. The engine, brakes, suspension and drive-train need to be in great shape. I'd like it to be leak-free (wouldn't we all - but this is a wish list) with a recently re-done interior. It needs to have a four person dinette.
Nice to have would be Thorley headers, upgraded rear suspension and either discs or recently overhauled drums at the back. In an ideal world I'd like a '77/'78 with a recent big block. I get the impression that the later coaches had one or two advantages like better waterproofing around the waist - but let me know if you think otherwise.
I realise that what I'm describing is an upper-end coach, and I have messaged a couple of people selling GMCs which tick several of those boxes. I don't expect one like that to magically pop-up near DC, but I think the West Coast is out in terms of finding one to buy, so if anyone sees one closer which might fit the bill I'd be really grateful if you could give me a heads up at Richard.Lister@yahoo.com.
Thanks for all the advice - this is a terrific forum.
Richard

Don't know the current state of it's availability, but I think that Jim Bounds has a nice coach sitting for sale in Orlando. The advantage would be that the coach could be properly checked over by a qualified source and be ready to go for a trip around the country. I could think of worse ways to see the United States!
If I had known what I do now, I would have certainly looked at the best possible coach to start with, rather than doing a restoration myself. I enjoy the work (I've always liked working with my hands on projects), and am hoping to have my coach in good, reliable shape this summer, but I've been working on the refurbishment for two years.
Enjoy your search in good health, and enjoy your trip!

Richard, I won't bother getting into the carb vs FI debate since I can rationalize either one. However, there are many types of FI if you decide to go that way (at least 3 of them exist on GMC's out there). In my experience TBI will get you about 80% of whatever FI can give you--esp for driveability, altitude adjustment, fuel economy and start-ability. The next step would be port injection which has more parts and just a little more of everything I just mentioned. Then you can go to sequential port which primarily will help on emmissions. The final step would be direct injection which isn't remotely practical as a retrofit but provides a quantuum jump in almost all areas with a big emphasis on more pure power output. Stick with port if you go to EFI.

There may be an inspector or two that will look the other way when the can't find the carburetor, but I would not count on it.
I took my '78 to a Smog Referee for modified vehicles. (I mean, duh. There are lots of hot rods out there.) It turns out that at the time Howell did not have a CA Executive Order for GMC Motorhomes. At the time they had and EO for their Jeep TBI and had applied to CA for GMC. (CA is not known for being prompt with these applications.) But with no EO they would not even put the coach on the dyno. I also had added Electronic Spark Control and so that was not going to be part of the EO.
I said to the Referee (a nice fellow) "You know it is making less smog, right?" (How could it miss with the O2 sensor correcting the mixture several times a second.) He said, "No doubt." I was shocked. "So I have to put the quadrajet back on to make more smog to pass smog?" He said, "I am sorry, yes."
It may well be that Howell has an EO by now. There may be another TBI company that has an EO.

George,
Thanks for the plug on coaches but the fact is yesterday I helped sell (none of them were mine) the last coach for sale at the shop. It seems that coach sales are going the way of home sales down here-- at the right price they are selling.
Scanning the posts here the way I do (as you could see from some of my comments yesterday I really do miss some of the important things but nun the less I just don;t have the time to read it all) Steve F. coach is a carbon copy of what Richard says he's looking for. Late last year, Steve allowed my wife, son & I to use his coach while we were visiting my son out in Sierra Vista. It is without a doubt the cleanest machine I had ever driven! It has everything and I mean all you can think of when it comes to what you need to enjoy a trip. If you know Steve, i was scared and actually wrote down everything I touched so i could get everything back just the way it was when I entered the coach-- he is the perfectionists perfectionist. If Richard is looking for a ready to go machine and Steve is actually seeking someone to take over what he has-- brother you need to hop a plane right now to Tulsa, I bet Steve will meet ya there with his rig and by the
time you get back to Sierra Vista you will be using first person words to describe things on the coach-- like MINE!
I see many coaches and Steve's is far above "top notch". So now that I have embarrassed him, I hope Steve will forgive me but you go through life being impressed by things and I think it is your duty to point them out when someone asks.
So Richard, if you are looking for a done up machine for you and your family, forget looking any further, get with Steve right now. Remember, the best stuff always sells first!

As someone in the thread said, air is power and thats about it. So a guy calls me and says he lives in Louesiana and is up on Colorado with his coach. He said it was not running very well and asked what he could do. I asked him how long he was going to be in Colorado to which he said 10 days. I told him you could readjust timing, get fatter jets and spend part of the time up there messing with it or he could just wait say 10 days and the coach would start running better as he headed home. If the motor keeps running but just runs badly, let it do what it will as long as you are heading home soon. You could twist the dist around a bit but put a mark where it was so you can put it back. I would also not race anyone at traffic lights up there. I mean it's all relative-- I'm not as fond of mountains as many people, thats why I live in the sand down here in Florida. my blood is too thin for the cold weather which BTW someone left the door
open cause it's cold down here. Retard the timing up there, baby it and hold on til you get in better air, your coach will thank you.
BTW, I do hope those with FI systems do not get too mad at me, I'm not attacking your idea of putting it on-- it just does not fit as a positive option for most of the folks I do work for. It is very cool to have the motor light up from a cold start and the "sweet Mother of acceleration " does look pleasantly upon FI systems. I will add though that the first year we did the drag race rally here in Florida I ran Larry sporting a direct port FI system-- I got a hole shot that snapped my neck but the next year I ran JayGee with a Qjet, original motor & tranny and I beat my time from Larry with it! I'm down with carbs on the straight line 1/4 mile hands down cause I did it!

Only way we'd go is with TBI, especially for the tripping you mention. We
bought our GMC in January '05, picked it up and took it to have a
Turbocity TBI installed on the way home (left it and picked it up a week or
so later). Worked on it getting all mechanicals checked/repaired/replaced,
and left Texas on the way to Alaska on July 1. We were gone two months and
had no trouble, except for a broken transmission shift cable on the way home
(which Bob drove with until we got back to TX). We had to leave it in gear
when we stopped; when he started up again, we could drive on off without a
warmup WITH THE TBI.
For mountain driving we wouldn't have anything but TBI. When we left Pueblo
last October, we followed our friend, who was carbeurated and had to slowly
climb the mountain passes behind him due to his lack of power. He plans to
eventually change to TBI for that reason--he drives to CO often.
I would not worry about not being able to get parts if it breaks down
because all parts are available at the parts house, including the computer.
Go for it. You will have the time of your life. We look forward to meeting
you on the road soon.

I see in some of the postings that there are several different TBI systems...TurboCity, Howell...and some others. Which one is the best to get installed?

Best? Them's warin' words, Pilgrim!
I don't know, but JR Wheeler put together a group buy with Howell. They modified their kits for the GMC Motorhome, and many have reported good success with it. It uses standard GM parts.

I intend to install the Howell system in my coach late this summer (if all goes well!) This can be made to accept electronic spark control and there is an add-on "EBL" that allows you to update the tables without the need to burn a new chip. This stuff really appeals to the Geek in me, and I have no dreams of saving money, or getting great mileage, etc. I just want the motor to idle and run as smoothly as possible, and have a new toy to play with!

We stock and sell the Howell units and have few people on our
consulting staff to give tecnical assistance. We will meet or beat any
prices onthese units as we carry them in stock .
Turbo City no longer sells the units for the GMC.

Dave,
Yours is the absolute best reason to add FI to your coach-- cause I want to! I felt the same way when I put the wild looking direct port set up in my coach "Larry" and loved to just pop the engine cover and mess with it. Watching the data screen on my lap top was cool and impressive and I would have had to go through that all to be where I am today. Would not change a thing.
The day I threw an alternator belt and the wires going to my sensor on the trigger wheel mounted on the harmonic balancer were ripped out of the sender from a Beretta and there was nothing to do but call Mr. Hook, I realized I was out there on the road relying on a machine I could not deal with when a problem came up I would have given anything to just have a blaster carb and an HEI dist. on the motor that I woke up and asked the question, what was I doing!
Different people have different epiphanies, for me it was the KISS system that won out.

Best? Them's warin' words, Pilgrim!
I don't know, but JR Wheeler put together a group buy with Howell. They modified their kits for the GMC Motorhome, and many have reported good success with it. It uses standard GM parts.
BDub has a very good piece of cyberspace dedicated to this <http://www.bdub.net/jrwheeler>

I intend to install the Howell system in my coach late this summer (if all goes well!) This can be made to accept electronic spark control and there is an add-on "EBL" that allows you to update the tables without the need to burn a new chip. This stuff really appeals to the Geek in me, and I have no dreams of saving money, or getting great mileage, etc. I just want the motor to idle and run as smoothly as possible, and have a new toy to play with!
No Authority, I.

I see in some of the postings that there are several different TBI systems...TurboCity, Howell...and some others. Which one is the best to get installed?
