will my 4 speed fit an 1983 318motor

go down to the local auto parts store and buy a pilot bushing for your year 318 take it home and see if it fits in the end of the crank if it does your good to go if not you will either have to do what adamr said although i agree with him that wouldnt be my choice or pull the crank out and have a machine shop machine out the crank for the pilot bushing hope this helps.
