Hello,
sorry its me again .... Does anyone know if you can still get quadrajet carbs with altitude compensation built in.
Wanting to spend time in much higher elevations when we get up and running. Seemed like that could save on gas, and perhaps less engine problems, as the air/gas mixture would be altered. Not got enough cash for fuel injection, so perhaps that would be a temp solution, if available....
cheers and beers

Seems to me that a TBI (Holley makes a kit) would be as cost effective as
getting one of those ACQJs set up properly. (After you locate one, that
is.) Talk to Larry Weidner about that as I believe he has a bit of
experience with those carbs.

I have a ACQJs off of a 75 Eldo sitting in my garage.
Make me an offer

Steve,
I spent a lot of time trying to make a ACQJ work on my 500. Eventually I did get it to work fairly well. But after all the effort, If I had it to do again, I'd save my effort and money for a TBI. The ACQJ has two extra rods in it. One is adjustable (thought the factory says it should NEVER be touched), and a transition rod that helps transition from low to high speed circuits. Trying to figure how the AC portion of the carb works with the primary and secondary rods and then how that all figures into the transition rod, really taxed my pea brain. The thing is a SOB to work with. Each time you want to make a rod or jet change, the top of the QJ needs to come off. That 5th rod (transition rod) makes working with it challenging. I went through many top cover gaskets and expended many expletives in the process. With the EBL and FI, all of that is eliminated and you do the changes from a laptop. I have a ACQJ and lots of jets and rods if you want to give it a try, but IMO you are not going to gain enough to make the effort worth it. Save your pennies for a FI unit. JMHO

I have tried two inexpensive solutions to high altitude carburetor issues. It is not very hard to change out main jets to slightly smaller jets. You can pull the top off the carb with it on the vehicle (I got the hang of it after pulling it off 3 or four times). Make sure you have access to a rebuild kit in case you damage the gasket; do not over-torque the front bolts or you can warp the carb. Jets are available at some carb re-builders. Go down from 72 to 70 if your current jets are 72. If you will be above 6,000 feet you might go down another step to 68 jets. Check one or two spark plugs before and after the changes (and at different altitudes); black sooty plugs suggest too much fuel, grey white suggest to little fuel in the mix. Check the color before you head up the hill and perhaps save out an old plug for color reference just after some highway driving. Second, you can advance the timing a few degrees (until just before it starts to
knock or to just before it stumbles a bit on starting).
This is just what I have done. Proceed at your own risk. My GMC has gone many miles with smaller jets even at sea level; I have burned valves on other vehicles by going too lean. I have used a pyrometer and fuel ratio gauges to be safe.

I see you are in Florida probably around sea level. I live at 4700 ft and have the stock jetting in my Quadrojet ,it runs pretty much the same as sea level but maybe a little less performance due to the elevation. I climb 9000 ft pases and it doesn't falter so if you aren't planing to go up to Pikes Peak or other high places I wouldn't worry too much.

Your biggest problem with the elevation change is going to be vapor lock.

Fuel Injection was the best thing I did. Well, it allowed me to do the best thing I did. EFI let me put on a computer controlled distributor. Now, that made a difference.
But... EFI is just like a GMC. JimK once said, "What's the difference between a GMC and a hole in the ground?"
Answer, "you can fill up the hole."
Fuel ejection fixes the altitude thing instantly. Never think about it. But then you will want spark. Then you will want EBL so you can make instant adjustments with a laptop.
There is an EFI forum. Before I got fuel injection I would ask there. You can save some money by planning ahead rather than my technique... I have had to modify my wiring harness for fuel injection about five times.
But, hey it runs sweet t sea level and Raton Pass.
The forum is GMCMI-EFI and is a google group. Lots of help there.

I've usually found that the biggest problem with high elevations is my own altitude sickness rather than the car's!
Even with fuel injection, I remember having my minivan floored while going up the last bit of Pikes Peak many years ago. Once we got out, even a small uphill climb was quite a chore.
For the GMC, I think that converting to fuel injection would be a whole lot easier in the long run.

Yosemite won't be a problem for the quadrojet, you should have an axillary electric pump if you encounter vapor lock. Lower gears like 3:70's would be nice especially if you have a toad in tow which of coarse could be un hooked. I presume you have reservations at the campground in Yosemite. You will want to approach Yosemite from the west because the climb out of Lee Vining from 395 (Tioga Pass) is kind of steep going up but doable
going down if you gear down and don't ride the brakes. I have gone up it with out a toad (I have 3:70 gears) You shouldn't have a problem in the Sierras just make sure you don't choose a road with too steep an incline. The engine should handle the altitude. If you are also going to visit Kings canyon and Sequoia
National park I believe some roads at Sequoia have a 23 ft size limit. The last time I was there I drove my 26 every where but the rules have changed. If you visit Lake Tahoe and are approaching it from Nevada stop by for a visit.

We bought our coach in Tuscon, and drove it over Vail Pass in Colorado at
11,000 feet with snow on the road. Best I could get was 30 miles per hour
until we reached the summit.

Steve and Debbie,
I wouldn't worry about the elevation. I have driven our coach from sea level to just under 8,000 feet with the stock Q-jet. The only issue I have encountered was vapor lock going from low to high. Generally the temps are lower at higher altitudes and the vapor lock has gone away, at least in my case. I have gradually been modifying the coach for use in the West and currently have a 3.70 limited slip final drive, an MSD dash mounted timing control (so I can add advance at higher elevations), and six wheel disc brakes with reaction arms (so I can stop). But your coach will do fine without all that stuff.
I agree that an electric fuel pump is in order to combat the vapor lock. I have one that is set up the same as Rob M.'s is set up, as a pusher wired to the tank switching valve. Even with that, I had severe vapor lock on a trip last July, climbing out of the Phoenix area on I-17, toward Flagstaff. Once I got up a bit higher, the coach ran fine. Fuel injection and a computer controlled distributor would almost certainly take care of most driveability issues. I have always had adequate power at high elevations.

Steve,
At high altitude, you carb tends to run rich as the volume of air decrees.
You loose power, so a rich mixture tries to give you more power.
Ignition timing can be advanced a minimum of 1 1/2 degree per every
1,000 feet of elevation.
Being in California, we climb out from sea level to 8,000 , so we know.
Having twin turbos helps a lot.

i saw elevation 6053 on the blue ridge parkway last fall. my coach which was fairly new to me and had not really had any repairs done by me at the time had no real issue power wise. overall i was impressed.

We also had no power problem on the south end of BRP, but the little rented Mitsubishi Eclipse the we drove over Tioga Pass into Yosemite was hard pressed to do 40 up that highway. Tioga Pass does top at about 10K feet at the park entrance. Both the park sign and my GPS said so...
