Help me with initial Holley Setup

Moper, I agree with priming the carb unless he's got an electric fuel pump, then there's no need. Definitely prime the oil system and get your dist. as close as possible. Excellent advice.

I'm not a big fan of plugging the power valve on a street car unless it's super/turbo charged, but kc8 didn't really state what his plans were. I just assumed street. Regarding the PV, do you really think his vacuum would be that low w/500 ci of displacement and that cam to require a 3.5?
