Alright guys, need some help on my next step in my new engine build! I got a 455 bored .030 over at 462ci, forged crank, eagle h beam rods, and ross racing pistons. Im wanted to make a 700hp(or close to it) pump gas engine, been looking a lot at the TIN builds and possibly going with a northwind intake, harland sharp rockers, kauffman or edelbrock aluminum 85cc heads to keep the compression low enough, what do i need to do to get 700 hp out of it? How much should i port the heads? 340cc is max that kauffman does on their heads. Am i going in the right direction? Still havnt made a decision on cam yet, they confuse me lol what lift and duration do i need? Just need some pointers guys! Thanks!
