I have a 1977 GMC Sierra Classic 3/4 ton that has a 350 4 bolt main crate motor. I have just completed putting in a Monster 700R4 transmission.

What I am asking is what would you all recommend to build an engine with around 350 hp and 400 or more torque, or tell me what you all did for modifying your engines.

Thanks
