Let's get some more info and pictures of the boat!!! If you post pictures, these guys can, usually, tell you anything you want to know about it. Sounds to me (based on what you have shown) like you got a pretty good boat, regarding the Chevy 496 and the Berkeley pump with a stainless impeller. What kind of hull is it? Have you had the boat in the water, yet? If so, how does it run?
Just keep reading and asking questions, and these guys will get you straightened out. That's how I've learned.

BTW, Tom at JBP is, by far, one of the best people to deal with, in the industry. Very knowledgeable and always willing to help whenever he can.
Good luck.
