I know I will probably get laughed at by asking but here I go.

Would a Ford 300 6cyl be worth the time to swap into my M-truck?

I can get a complete engine, wiring etc and a C4 trannie for basically free. (friend has one from a truck he is using as a donor).

I know a V8 would be better, but the $0.00 price tag entices me.

Would the effort to do the swap be worth the gain?
