G'day,
I sent the following query to Holley's Reman Division Tech Support email:
I would like to know the Rochester OEM part numbers for the carbs Sales
Number: 64-7256 & 64-7259 to verify that they are the correct carbs for a
GMC Motorhome. Thank you, Rob
I got the following response:
7045254 = GMC
7045554 = GMC
7043254 = GMC
17056258
17058250
17058253
17058553
17059258
17059259
17055645
17055635
17058254 = GMC
17065609
17057258
From the info that has been provided in previous GMCnet messages I added =
GMC.
Someone that needs a rebuilt carb will have to order one and see what they
get and how it works. Considering the fact that Pace Performance will sell
it for $208.69 (including core charge) it would be worth a shot. If it
doesn't work properly I'd think it would be covered by warranty.
Assuming that Pace is not "The Pirates" Larry was referring to! ;-)

STOP THE PRESSES!
Look what I just stumbled on to on the Holley Reman website:
http://www.holley.com/BrowseCatalogs.asp?Catalog=Reman&Page=261
The first numbers are listed here and continue to page 264.
Rochester
O.E. Number Sales No.
7043254 64-7256
7045254 64-7256
7045554 64-7256

17057559 Not listed
17058254 64-7259
17058559 Not listed (CA Carb)
Now whether they have these carbs in stock is another question!
Here's the contact info I would suggest that someone in the USA give them a
call and see what they can find out:

Steve,
You're not wrong!
I did notice something interesting:
We can Restore your carburetor
Or call with a carb number we have lots cores
Chris, it might be worth your time to give them a call to see if they have
any cores for a GMC!

This makes Paterson's price appear reasonable considering it then will be,
for sure, the correct Qjet for the GMCMH.

Any of you fuel injection guys out there want to part with their old correct carb?
I'm looking at over $600 all said and done. Fuel Injection kit is looking good to me right now...
What's funny, is this carb actually works pretty good considering the accel pumps are crap.

So just get a parts kit and replace/repair the accel pumps. Those parts are part of the Qjet overhaul kits. It's not that hard to rework a Qjet.

Do to a bad rebuild my motorhome carb was shot and useless as a core. I'm using part of my old carb, part of a 454 carb, and the coach runs much better than it ever has. While I would love a motorhome carb and have posted for one on the flea market area, I don't think not having one is all that big a deal. You can also contact Joe Mondello. At Eastern States he said he had carbs that would work just fine for a motorhome 455. I think he wanted $250-$300 with no exchange needed. It's nice to squeeze as much performance as you can from these old babies, but it's probably not that necessary for most people...

Yeah, I may do just that for now. The other half wants to get me fuel injection for Fathers day.

@Robert- Was it a spread-bore 4175? (I know of a torker/standard-bore attempt that was a disaster.)
Folks, I am simply trying to open conversation to steer things the way the airbag situation went. One Source-Many source. There are 4-5 of us on this single post that don't have that magically #'rd carb to route through Dick's Carb mecca. Wish I did, but I don't so $2000 or $260? I am still counting change to save for airbags,wheels and tires

My own "progress" so far:
Tires: Discount Tire in New Braunfels, TX where I picked up my coach in May 2010.
Shocks and brakes: Local frame shop in Oklahoma City, 2011.
Airbags: Sullybilt at Shawnee convention/rally in Mar 2012.
Wheels: XD-775 Rock Stars (chrome) at Discount Tire 4 miles up the road, spread
over 3 months (2 wheels per month) in Summer 2012.
Set priorities (safety first) and spread out the spending!
Still need work on fuel hoses, but beyond my DIY capabilties. Major fuel leak
HAS been eliminated.

The difference between the butchered Q-Jet that was on my 455, butchered so bad the vacuum pot to open the secondaries was removed and a screw put in the port. to the Dick Patterson Carb was between night and day. Dick looked at the bad carb, and did not even hazard a guess where it came from, but it was not acceptable as a core.
Settle for the best, get a Patterson.

I have had experience with the Holly carbs enough to feel they do not work well for the GMC, you would usually need to build a dog house and in the end really, the perform is not there. A "new" carb also would probably not offer the best performance for the GMC. The remanufacture we do and I also know Dick Pattersons is a well filled with unique things specifically tuning the carb for use in the GMC. Among other things, we change things like the powen valve setting from dumping buckets of fuel. There are other special things that a "new" carb or a carb put together in a generic fashion would not have.
Your best bet is to send us or Dick your original carb and have it remanufactured itself. That way you know where the beast came from, it's "trauma" and you know it is what you had. Exchanging carbs is not a good thing to do at least in our application.
And as far as the thread about FI or carb-- most of you know I do not FI-- did it and vowed never again. Hey, it's one of those things like tire brands, oils and fuel you like-- everyone has an opinion and if you wanna know which is best ask one of the people with an opinion and they will tell you which one to believe-- usually it will be their idea! I have never seen more mileage or over all performance pick up switching so why would I want to... Just how I feel...

Pete,
When I bought Double Trouble it had a Holley on it. Ken Frey tuned it and it ran OK. However, I found performance at highway speeds
didn't meet my expectations so I got a rebuilt QJ from Dick Patterson. When I removed the Holley I discovered the reason the Holley
didn't perform as well. The Holley's secondaries are MUCH smaller than the QJ.
What was most interesting to me was when I fitted one of Dick's re-curved distributers the performance got even better!
Unfortunately I can't tell you anything about the mileage as I've never checked because there's nothing more I can do to the engine
(at reasonable cost) that will make the gas mileage any better. I drive at whatever the speed limit is: 60 - 65 - 70 - 75. If you
want to get good mileage drive at 55 - 60.
Or as Gene notes: Mileage in a GMC will be 8 - 10 mpg.

Rob M.

PS - I sold that Holley at the Amana flea market for $25

From: pete
I have plans to purchase one of these if my currently functional QJ(non-correct#)starts misbehaving. $260. new delivered from
Holley. 90 day warranty.
A couple of brave souls have this set up and have brazenly spoke up and have reported identical mpg to QJ. Secondary spring fine
tuning was all that was necessary, experimenting with power-valves etc. resulted in returning to out of box set up.
Any updates Holley lab rats?

We carry Patterson's product and consider them the best, however for those
that want one that is less in cost we provide a unit that is rebuilt by a
local firm.
We have had larger firms Quote us on rebuilt units and when we received
them there were few things that did not work.
I agree with Ken, your wasting your time as there are many things on the
carb that is different like the throttle linkage connection, lower linkage
interferance with manifold,etc.
