It's going to depend on CID, compression ratio, and cam choice. If you provide me with the CID and compression ratio, I can specify a power piston spring that will work for what you are doing.....Cliff

Cliff [Ruggles]JET
Quote:
The engine is a 400/462,just under 10.1comp. SDPERFORMANCE [Ruggles] cast intake. RamAir Restorations Ram Air manifolds[ceramic coated] 2 1/2 XPYPES exhaust. The carb is that later year Buick 800 cfm with the APT adjustment. Just a note to those reading this, I too at one time bought a Q-JET from Jegs,it did have the chevy fuel inlet and the carb ran like crap. I did send it to Cliff [6yrs ago-ish] and he had a list of things not done to the carb as to where half the carb was working. [it was a piece of junk] Cliff did repair the carb and it was great. But just think of all the added xtra cost of buying a newly-rebuilt carb and having to send it out to be made right. Cliff is worth the wait

Every time I type in 7029268 in ebay collector car parts one comes up. Unless your GP is a 4 speed, thats the right one for your car. They vary in price. There's a lot of them out there; they went on every standard engine 4 bbl automatic Pontiac in 69 with a 350, 400 or 428.

The quality control of the "remanufactured" carburetors has went from "pathetic" to "not worth two squirts of duck poop" in recent years. They have so many problems I could write a book on them in this response.
Instead, I'll just say that we don't want any sent here, and are no longer working on them for any reason. In the amount of time I spend trying to get them up to par, I could have built at least two original "virgin" units from the ground up and ended up with perfect results right off the bench. The "reman's" are so "hacked" up these days, and the castings are soft from the acid bath they get, we're just "polishing turds" trying to get them up to par for the customer. I would also recommend for anyone reading this to avoid the electric choke Marine units being offered on Ebay. They are nicely painted black mid to late 70's Caddillac cores that are WAY, WAY off the mark for any Marine application. Had a few end up here in the last year or so, and don't want to see any more of them either. A guy is better off to get his own core, some good parts, and go after the deal himself, than to throw good hard earned money at some generic/commercially remanufactured POS......IMHO......Cliff

That application should make at least 11-12" vacuum at idle speed. I'd use the light blue spring that we have in our PP spring kit.....Cliff

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
