Looking for a complete roller

I dunno why the last post turned out that way, sorry. I need something that will handle 600 hp. It had a 850 on it with headers that were to big. 950 carb and my new TTI headers, I will do 10 or 15 more pulls and hoping to hit the 600 hp mark as right now it`s only 570. The torque should increase as well. Fun street/strip motor. Roll up on the 91 ethanol pump at a ton of local stations and go racing!!!!
