OK... I've burned sage over the "rebuilt" 904 that had been the nightmare. I'm pretty sure I found and resolved the issue that caused all the problems.
Question... can I use all the new, upgraded guts out of the 1965 Slant 904 and put them into a 1965 SB V8 904?
And the torque converter?
Both pushbutton and ball & trunion.
