They made just about 720 hp on the dyno at 5800 with 5.5 lbs of boost (blower underdriven 7%). When I purchased the boat the dyno sheets said 800 hp but I didn't like the setup so we lowered the compression ratio from 9:1 down to 8:5 to 1 and we put a smaller cam in it, I wasn't looking for max HP. The cam is relatively small considering everything else. If memory serves me corretly is has .580./.590 something lift, I don't recall duration off the top of my head. Basically, it's two steps up from the 525 SC cam.Originally Posted by ratman
If I had to do it all over, taking JC's advise, I would have had a hydralic roller cam put in, along with Cometic head gaskets.
All in all they run good and have tremendous torque. Push the throttles forward and they go! No flat spots all the way up until the sticks are to the wood.
