Hi, I am new here, so be kind. I am trying to figure out how to set up my distributor. I have a 79 Camaro, with a 400ci small block. 9 to 1 compression, L79 cam (224 at.05 and .447 lift ). Dart II heads, (200cc runners) Dart II dual plan intake with Holley Avenger 770cfm carb. 2400 rpm stall converter in the TCI turbo 350 auto trans. 12 bolt posi rear with 3.73 gears. MSD6 ignition hooked up to the HEI distributor. The distributor currently has 20 degrees (at the crankshaft) built in, all in by 3000 rpm. Do I need more in the distributor? I am starting at 14 degrees initial advance. I have an adjustable vacuum advance, Where should I set it? Thanks.
