looking for a few hp, and by a few i mean a lot

so i've come upon the conclusion that i need a 502 to replace the 7.4l i have now. checked out a couple engine dealers and 1800runsnew seems to have good prices.

now to the question.
what do i need to do to get the 502 crate motor working. im sure i can't just open up the crate and put it in the boat. already have lightning headers so the exhaust is covered. any machine work? what other parts, other than a fuel pump. in the end i hope to get 850 hp blown, would this be a good engine to start with?

850HP, No!

600-650HP, OK.

I have 2 with prochargers and they run great. You can probably use the parts off the 7.4 to complete the motor. Good Luck.

what exactly is required to complete the motor?

oh, and Ken how much hp are you getting out of them?

I have a spare engine for my boat that I want to sell. I is a 500 bulldog, with a 250 BM, with a PFM cooler. It run's 6 pounds of Boost, and makes 675HP on the dyno. It is complete, with dyno time only. It only has 80 hours on it since it was new. 12,500
