It made 584hp/560 lb-ft. The power was all in by 5900rpm. I didn't have to turn any revs at all to get the power out of it. It was a really mild (in terms of duration at .050" for this size engine) camshaft. I bought the Comp grind from Keith Craft to try out but have now decided against it. The Jones cam needs a lighter valvetrain than what I had to work effectively. I also have some modified hydraulic roller lifters from KC that should help out with getting the most out of the camshaft. Keith estimates 650hp with his cam and lifter setup. As good as these heads flow, there is a LOT of potential in this engine.
