32 total and use a Vacuum distributor, full y advanced by 2500 rpm. Also try to use the same grade of gas from the same label. Preperably Sunoco. If you have to use E85 for the extra octane only if you feel any detonation, which would be caused by your cam choice.

it is a non vac distributor and i was recommended to run 18-20 initial with the cam i have as it is quite large, with using the black bushing which limits at 18*.

i read those posts and it seems the 1 heavy silver and 1 light blue springs seem to work well, i will try that i guess.
