Thread: Which intake should I go with?

Tweet

Generally speaking, I've never really seen carb adapters do anything but mess up the air flow unless they are VERY carefully matched to the manifold top and carb base... They also mess up the velocity due to the venturi they create........ But, I do know that intake works good with a Q Jet, or the Holley spread bore 650!!!!!

it works fine but would like to replace it with something else

If you have an RPM Q-Jet intake, bolt a 750 or 850 Q-jet on it and you will have, in my opinion, the finest carburetor/intake combination there is for the street. Tiny little primaries for excellent mileage and throttle response coupled with humongous secondaries for when you rug the throttle and the carb goes B-WAAAAAAAAAA.

I was told for this engine that a 750 would be too much...???

With a square bore carb, it might be but with a Q-Jet, it would be just right.
