    There's probably a million threads on this already but I'll ask anyway. I'm looking for a carburetor for a Chevrolet 350 ZZ4 crate engine. Auto trans so need vacuum secondaries and want manual choke. Any recommendations regarding brand, CFM, jetting, etc. would be welcome. Thank you.

    Take a look at the new FST carburetor line. Both Summit and Jeg's carries them. I bought the 750 RT carb and it has a ton of nice features. I will be getting a 600 VS when I get my free govt. money.

    Why do you want a manual choke?

    The turn-key ZZ4 crate package was sold with a Holley 750 cfm carb.
    That should be plenty for a 350 hp 400 ft/lb engine.

    The Holley 4160 should work for you.
    It has an electric choke but that’s a simple thing to wire.

    Even a 600 cfm would be plenty for 350 hp.

    Probably get a little better throttle response too with smaller primaries.

    Was plenty for my 461 BBC that ran 11.70's with a 600 Holley VS.
