I wanted to do a 2spd rear on my fummins.

you can't chip or tune a 4bt its a mechanical motor. as for the trans. its what i have around. I am building it on a small budget. like $500 parts budget. so motor trans and clutch are not included as they are sitting in the garage. as for why a 3/4 ton trans, its a torque monster for...
