Still building mine but I went ritter block, ported magnum heads hughes 1.65 rockers, super victor intake, twin 76mm with air/water intercooler. Motor is bored and stroked to a 426cid, should made 1000hp on pump and 1500hp on c12, fuel injection with megasquirt 3x system. I went with the ritter block due to extra insurance on enhancements over stock and priority main oil feeding, that and r3 blocks are hard to come by. I have the XR cast iron block. Once it's all done finally will post numbers on my build thread.
