Can anyone please tell me what the correct measurement s for the hole in which the crankshaft is supposed to have for a 4 speed in the rear of a 383 Crankshaft? I have a rough measurement from the 383 engine which came from my 65 Sport Fury which came with a 727 automatic and the 440 which came in a 65 parts car which I purchased with all the 4 speed stuff not installed. It seems as though the 4 speed would have never worked with the 440 as it doesn't have any hole in the crankshaft. My...
Drilled for 4 speed or not?
