If you're looking for a FE that "likes to rev" than you need to stay with the stock stroke. My KC 482" Pond (4.25" stroke) is done by 6000 rpm. But... at that point I'm already at 600+ hp. 550 hp is very doable with a stock stroke, matching cam and a set of his stage II CNC'd heads.

Talk to Keith, even if you're just in the planning stage. He's very helpful, no commitment required.
