SBC 350 Carb Recommendations

Imo the 750 cfm 3310 for example is a better carburetor than a 770cfm street avenger. These street avenger carburetors are just factory replacements not hi performance carburetors like the Holley 4150 series, Speed Demon and the Quick Fuel carburetors.

F-BIRD'88 The 750 cfm carb is always the best buy for a high performance SBC.
You don't give enough specifics to get beyond that.

454C10 If your intake is a spread bore then you should use a spread bore carb.

I like the edelbrock RPM intake (not rpm air gap) with a holley 3310 (750 vacuum secondary) on just about any street/strip chevy V8 build. Works well on street driven engines up to 450hp.

Get a 750 cfm if you get a vacuum secondary carb. Or a 650 cfm with mechanical secondarys.

SBC 350 Carb Recommendations

Hey guys, I'm new to the site (although I've been creeping in the background doing a lot of searching).

I'm looking for Carb recommendations for my SBC 350 that I'm building. From my searches, I'm torn between a 650 and 750 cfm.

Here's my current engine setup that I'm building:

1974 SBC 350 - Stock Bore
Flat Top Pistons
64cc Edelbrock Performer RPM Aluminum Heads
Edelbrock Performer Intake
Comp Cams Thumpr Cam
MSD Pro Billet Distributor, 6AL box and coil

I realize the Thumpr cam isn't a high HP cam, however it has what I'm looking for. I have done some research and see that the vacuum pressure is the biggest issue that I may have, so I want to make sure I purchase a Carb that will work the best.

Any recommendations are appreciated!
