I have a 76 power wagon with a 400 and 727. Reverse went out and don’t want to deal with an auto transmission in it.

I also have a 76 power wagon with a 440 and a 4 speed and wanted to swap the motor and transmission. Will everything bolt over with minimal fuss?

 

yep

 

It's just turning wrenches and swapping parts, it doesn't get easier than that swap!

 

yeah, no sweat with that setup! go for it!
