I built my (High Strung) 600HP 468's knowing that I would have less torque, and I would have to spin my engines to 6000RPM to reach my max HP. My reasoning was that it would be a little easier on the drives. Granted I have a considerably lighter boat than you. I know you want torque in a boat, but I do not need as much as you. I think you can build a pair of great 496's for your application.

I also think you need to ditch the stock manifolds and let them babies breathe, BTW what are your performance goals.

I had a friend that use to have a HEAVY '86 Top Gun with 700+HP solid roller 540's and he was going through a TRS/month. He also drove it like he stole it. Money for drives were not an issue. Babying it was not an option.
