I recently acquired a very good running '60 401 Nailhead. it was in an OT vehicle with a 3 speed Ford manual trans behind it. I do NOT want to try to fit the clutch linkage into the '40 Ford coupe this will be going into... So,.. I would like to sell all this clutch stuff that fit the back of the Nailhead and adapted it to the Ford 3 speed trans and put an automatic trans behind the 401 before I put it all in the '40. Question therefore is, what auto transmissions, flex plates and converters will fit the engine... and are there adapter plates commercially made to match a turbo 350 to the 401? I am going to complete the making of my memory of the car that got me into hot rods way back in early 60's by putting this engine/trans combo in my '40 and removing the monster chevy Big Block.
