They also have the holley carb with their name on it with an intake, and complete intake kit, and all mounting hardware for only 80 bucks more

they are usually found in dumpsters and the like.

Man that holley in the pic looks good and bet ags goes through it like a water hose. What about when engine backfires and blows power valve

One small vote in favor of the Q-jet. I've had one on my 350 for twenty five years

I took one off a 79 conversion van and recalibrated it to match a stock 72 truck. it runs great and the electric choke is more reliable than a divorced one. plus it moved over 12,000 lbs back from DesMoines with not a single problem.

We never had a problem with a Quadrajet, all our trucks have 'em. My Grandpa taught me how to rebuild and tune 'em when I was 15 too.

Okay to be fair I remember when I had a Q-Jet on a 455 Buick and that big ole boat Electra 225 moved!

But I would still rather have a Holley than that ugly mug of a carb sitting on my engine.

prostreetC-10 · 08-23-2009, 12:48 AM

I couldn't do that to you Jim. It would just confuse your motor. If your intake is a spread bore, you would have to get an adapter to bolt up performance equipment and that might get your linkage and choke all messed up. The "waking-up" of your motor would probably float valves, bend pushrods and crack the case on that T-10. You probably wouldn't send my carb back after that and I'd have to report you to the board admin..........see how bad this could all turn out?????

Guess you would finally get into the 13's though......LMAO!!!!!

Nice try, but the Performer RPM spread bore I am going to install accepts both carbs.

Thank you Jim .
My truck is a total survivor and it was sitting for 10 years. Changed the filters and she is running awesome..Lots of torque...My wife and kids fight to get a ride in it...Q-Jet are complicated and you need to be on your game...If you want cheap ( inexpensive ) and easy = Holley. If you want something that is the real deal = Q-Jet..

I'm running one the only issue I had was it was loading up with fuel (flooding).
I checked the fuel pressure and was running twice the pressure it should be.
The quick fix was installing the magnafuel pressure regulator.

I had a '67 Pontiac Firebird Sprint, with the 230 OHC engine, dual exhaust manifolds and a Q-Jet. What impressed me was the way it could handily clean up a 289 Mustang. I put a set of baby turbo mufflers on it and had true dual exhausts when I had the pipes run from the stock manifolds.

Shoulda never got rid of it.
