Im guessing 470/450.. Reasons, relatively small cam for the cubes, and mediocre heads for such a big bore.....

 

I'll take a stab at it and say youll be around 460 RWHP. Thats only a moderate sized cam for the displacement you'll be running. Go larger and you should be able to knock on 500 RWHP's door without too radical of a setup.

 

ok guys what cam are talkin to achieve 500 rwhp?
