Do a search on here for threads where we've discussed this at-length before. I think there's more in the Stroker section especially. Anyway, I don't know your engine, but with that cam, the rule-of-thumb by most cam manufacturers is 18 to 20° initial (base timing), and if yours has efficient and matched parts, use enough mechanical to hit 26 to 33° total by 2500 or so. The only way to know exactly what numbers is by testing and tuning. This is the big payoff where you let it make the power it can, so take your time and do it right. Here is a random and basic overview that may generally help. GM numbers are similar to Ford and vice versa.

Thank you very much .... I did do some searches and found some good info. I was just hoping to get a dyno type result on a stroker 390 and what they got as max hp with what timing.

thank you
