STreets, The 64 came with as much as 425 hp 409 I have the frame already cleaned, treated for rust ,primed and painted.It was already in good shape before I started. Now that I am close to ready to go back together I am having some 2nd thoughts. I have 3 complete posi. units,373-411 and 456.Now I am seriously thinking of putting a 9 inch with disc brakes out of a Lincoln. This thing is going to snowball on me if I don't get a grip.
