360, carb jetting recommendations

Not too much carb. Hard to overcarb with a vac secondary. Just run a tight enough vac secondary spring so it doesn't bog when you nail it and your good.

^^X2 on 72's and 76's to start^^ Idle vacuum will determine what power valve you need. Hard to guess that since you don't know the cam specs. When you get it running and the idle adjusted (in gear if it's an automatic) take a vac reading then use a PV that's 1/2~2/3 of that reading.

After you get those things done you can run it wide open (you need a fresh set of plugs) and have a look at the plugs to see what the jetting looks like. Abody is correct that the only way to get it right on is with a A/F meter but you can get it close if you know how to read plugs.
