Has it been on the dyno yet? MRL just posted a 416 inch motor, same heads, pump gas, .620 solid roller, performer RPM intake... made i think he said 584 HP with a fuel supply problem, figured close to 600 was possible with fuel issue straightened out. 14 inches of idle vacuum too.

Sorry to disappoint,
Block machining starts next week, ain't using a roller no way no how, dual plane will not suit this build, this cam might make 14" vacuum cruising @ 3800 rpm going down a mountain with the throttle closed, and most certainly will not approach almost 600HP. Hang on tight it's gonna get interesting. J.Rob
