Okay so forged eagle cranks, forged je pistons, and forged gm rods are not going to make it to the 800-850 range? I do plan on running the iron heads, and the motor is built with arp bolts now, and real good head gaskets. I realize those will have to be new when we do some more work on the heads before the blowers go on. What hp level can my bottoms ends live at? I thought I had read lot's of story's of people strapping some big stuffers on there 500's and having them live at the 800 mark? (the only stock part in my bottom ends are the rod's themselve's)

The internals are the stock SC 600 parts. Mine are 98's, which for some reason, are listed as a one year motor. They have the 91-94, then the 98 . Not sure of the differences between the older SC 600's and the 98 model year???? But I assume it has the GM rods as well. The motors have had msd ignitions installed and spin to 6000 rpm's. I couldn't be happier.

With that....My advice would be 8-71's with 750's at no more than 7psi with roller cams. Should put you at about a tick under 700hp at 5500 and be happy.
Marine motors need a big safety factory built in over street motors.
A fraction of a second of ping can junk a motor with less than the right internals. If you want that 800-850 your going to need some good stuff.... Merlin or Dart with American made cranks and I or H beam rods, etc.
Happy boating and be safe.
