switching from a 3 speed to a 4 speed?
I currently have a 3 speed in my 71 challanger that is mated to the 318 small block. I am going to eventually run a 440 with a 4 speed. My question is can any of the parts off the 3 speed be used on the 4 speed? I know the bell housing and clutch will need to be changed, but what about the rods? Will the driveshaft need to be changed? I am looking for a a-833 4 speed currently but the 440 will not be in the car for a year or so, money is tight. I also heard alot about the Tremec 5 speed transmissions. What needs to be done with that and what does that cost versus the 4 speed? Thanks for any help.
