Old engine with a newer post 1968 tranny is a bit of a problem...you will need an old transmission to match, or you can get a modified torque converter that will mate the two of them together. I just got the TC from Hughes Performance; it was $220 plus shipping. It has the small snout on the front to match the smaller crank pilot hole that is in the old engine's crank, and it has the right number of splines to fit the input shaft on the later tranny. Or, you could pull the crank out of the early engine and get it drilled to match the larger snout of the late TC. One thing you can't do, though, is turn down the snout diameter on the later TC to fit the smaller crank hole. Not enough metal on the snout.
