Re: K30 Downgrade to Cummins Project
The Cummins will definatly be the way to go. The only thing bad is the rotary pump. I will never make the power of BB horse power wise. Swapping to a p7100 pump will let you. Either way you should easily have more torque than the big block. Just don't forget that the Cummins is heavier so you will need to build a little more torque to motivate it. My 700HP 12v got 18.5 MPG driving in traffic.
