I just saw your other thread about headers where you say you've got a 425. The correct engine should have been a 400 so that's been changed. Check your transmission tag, on the passenger side of the car to see if the autmatic is correct or if it's been changed too. To the best of my knowledge they never put 4 speeds behind 425 engines. But that should use the same crankshaft as the 1965-67 400 engines. Finding a factory 4 speed crank may be difficult and expensive when you find it, but if you really like the 425 you could explore that possibility. John
