Thread: is a 750 holley to much carb for a 350

At what RPM is the power dropping off at? based on the cam and heads you are running your intake may be part of your problem,a Performer RPM or Weiand Stealth would be a better choice than the Performer you have which is making its power from off idle to 5500 RPM.The standard Performer works well with a cam of lesser duration to improve mileage and low end torque.As for the fuel pump SBC performance pumps are priced reasonable so changing it would not be a bad investment anyway.

Bless you TechInspector.

I've been arguing this point for years and I usually get the old carb-size with VE tossed at me.

For street use, Skids72 comment on good atomization probably applies, but perhaps not.

I run a single 750 Edelbrock on a 462" and at part throttle - meaning light throttle in the 2400# Deuce roadster - and subjectively viewed, vaporization is probably doing ok.

Over at "GoFastNews" I think they have an upcoming article on running a huge by large carb and initial reports are it's doing ok.
Not sure if it's strictly for racing or street running as well.

Little brother runs a pair of 1100 cfm Dominators on his 500 cid DRCE engine and the car has good manners at part throttle operation - which means he's pretty much running on the idle circuits.
The car, an about 2500# Henry J tube framed drag racer.

Going the other way I've run a 600 cfm smog Holley on the 32 with the 462" Buick engine and it ran well.

Interestingly, mileage was about the same.
