    Default 355ci SBC, newbie needs help.

    Hello. I have a 1973 Nova with a 355ci SBC, HEI converted, small cam 292/525 , Weiand 7546 Intake, 1.5 roller rockers, 4.10 gears and turbo 350 transmission.
    I just put a rebuilt 4777-3 on it and in between 1500 & 2000 RPM when WOT it bogs. I figure larger discharge nozzle or 50cc accelerator pump?
    My discharge nozzles are a 25-28 and jets 64-73 I believe, power valve is a 4-5. I have approximately 11 inHg vacuum.
    What's a good starting point in regards to jets, discharge nozzle, accelerator pump/plastic cam color, etc. for my 355ci SBC setup?

    Go to the carburetion section, and look at the stickies. Your problems are discussed/covered in there. Thanks, Sean
