Need new carb recommendations

[Dredgeking]

I have a ZZ4 350 ci GM crate engine that makes about 345 hp. It has an automotive 750 Holley double pumper carb on it now. The carb is not flowing fuel out of the rear two bowls. So, I want to change it to a marine carb that is closer in correct size. Maybe a 650 Holley marine carb. I just want to hear what you guys were using on your SBC's. The easier to setup, the better.

Barry Grant manufactures a carb that is specifically calibrated to the ZZ4 motor. IT IS NOT a marine carb but very close... if you ask nicely they might do a marine carb of the same size with the ZZ4 calibration...

650 is PLENTY to feed that motor and what i'd run if it was me..

i really LOVE the BG Demon stuff... vs holley... they are good right out of the box for most setups.. with only minor tweaking.

you also have the option of the edelbrock Carter AFB style or quadrajet...
