I am going to put a 4-spd to replace a 727 and if I am not mistaken when you go from automatic to a standard you need to put a pilot bushing in.
The pilot bushing goes in the end of the crankshaft and centers the transmission input shaft with the crankshaft. The manual transmission's mainshaft is not completely supported without a proper pilot bushing
better check to see if your crank is bored for a pilot bearing, also if its a 440 is it internal or external balanced. There are many problewms doing this conversion I know i'm in the process, any questions just ask
BUT BUT BUT...the cool Mopar roller bearing pilot that fits in the torque converter centering ring doesn't require machining of the crank, just cut enough off the transmission input shaft to clear.
