Hi all,
I've read these forums for the past few hours trying to figure out where I need to go with my setup. I got some good info.
Hull is 18' Starbuck (jet) with the stern molded to match the contours of the pump. Current pump is Berk A, aluminum impeller, and seems tight.
Engine (being built) is 496 roller with stock 990 heads. (Forged internals) Builder says easily 600HP on pump gas.
Questions: What max. RPM/torque should we cam for? I am thinking something around 5600?
At 600 HP, do I need to change to bronze or stainless?
I realize there needs to be more information to figure this, but hoped someone out there could get me in the ball park. This is not a race boat of course, but a lake hotrod that I would like to hold together.
Thanks!
