I got a 1991 f150 with a 302. Long story short I blew the motor up and did a motor swap and my efi stuff was shot and didn't feel like paying over 1000 dollars to fix it so I did a carburetor swap(cheaper and may be going back to efi if I get the parts truck am looking at) and the E4OD won't shift passed 2nd gear with the carb swap and I got a rebuilt c6 sitting in the shed from a 79 f250. How much work would it be to switch to the C6. Please don't start with the "why did you go back in time with a carburetor and why you want to go to a C6" I want a C6 with it being made in to a rock crawler

 

Shouldn't be a whole lot to it the C6 is a simpler trans, no computers.
