I build motors for a living. The big block is the way to go. In the right configuration it can be as fuel efficent as a small block with out the drawbacks of the small block torque issue. Puls if you ever go to sell your truck it will usually biring more money for it. If you need some specs on a motor combo or prices for parts drop me a message. That goes for all on the board too.

I'm interested and I thought it would be worth talking about on the board. How 'bout it?
