Stock rods and heads? 8:1? Hairy stick? Not gonna' run for sh!$ by itself. May not run for long on a big shot with stock rods. Might consider stepping the pills down to 125-175.

I would hope you would run better than that - My 350 has gone 7.18 on motor. You have too big of cam, not enough converter, and heads that are great for mid range
