I did rip front end apart to bits and pieces,rear end will get the same once i get it fitted to the truck.
If i can run it an hour or so without issue, i will then pull transmission and clean,reseal and dress the flywheel.
If i am not happy with it, the 318 for the dart will find a new home.
Similarly if this poly falls thru and is junk, the 408 may come out of my w200, a 12 valve Cummins which I have laying here may go in its place and the 408 into the Polara.
