400hp 360

I got 449 hp on the dyno from my 72 340, the only question is how much do you want to spend. It runs on pump gas with J heads. I wouls guess if I went with some aluminum heads all ported up i could get closer to 500. If you want I can look thru my stuff and tell you the basic recipe. I think I spent too much on the cast heads... I would reccomend going with Al heads from the start and making sure your bottom end can take it. I think we went to 6200 to get that HP out of er.
