Well I would like to tack it to the max of reliability. I like to build things that I don't have to work on all the time. I was a boat maniac for a wile. I have never built Chevy 6 I can do fuel injection turbo's and SC chargers. What I really need to know is what is the max torque it will Handel with the stock crank, and if there are stronger cranks available, and what the week points are. It will need 300 +Hp to live in my world and do that all day long with no issues.
