340 rebuilt, Slant 6 coming out
Old , high-mile, non bolt-in junk. Not in my cars. I have an non-Chrysler SBM engine, ATI Turbo 400, and Strange Dana. Non mopar from front to back.
Put good parts in, and never worry about them again. I suggest an LS, since it's not numbers.....
I'll bet it's cheap and easy to change gear ratios in that ford rear.
