Cummins to sm465 in k10?

I have a 72 k10 that I really want to convert to a 12 valve Cummins. I have a 350 sm465/np205 in the truck now. I would like to keep the 4 speed as I don't really need overdrive due to 35's and 3.08 gears. Does anyone have links or maybe previous builds with more info going in a 4x4? Thanks

Re: Cummins to sm465 in k10?

they did offer 4bt in gm p30 bread trucks and some were auto and some were stick . so there should be factory parts out there . this much i do know . sorry more of a gas guy . and i dont think that 12 bolt 1/2 ton axle will live long under the power of a 6bt engine . and the ball joints in the dana 44 front wont like it .

but others have done it so yes it can be done .
