Hi Tigertracker
I have a 514 crate motor from Ford Racing. This is a stroked 460. It originally dynoed at 600hp, however, for streetability reasons I swapped out the original single plane Dominator intake for a dual Plane Performer RPM and put a Holley 850 on it. I'm guessing that it's in now in the 550-570hp range. This motor also comes with solid roller cam and roller rockers. The cam is a bit much (254/258 degrees duration) but in my opinion, very streetable. You can find a lot of information about Ford crate motors and racing parts at
www.fordracing.com/performanceparts. Hope this helps
