If this has already been addressed by the great and powerful Ford gods then kindly point me in the right direction. If not I humbly present to the benevolent Ford gods a sacrifice of my first born. In my 47 Ford coupe I am putting in a 351W from an 80s truck. The transmission is from a 71-72 302 Mustang (PEE AC4 D 27PDAJ25). I have determined that the transmission is a 157 tooth bellhousing (5.875" BH depth, and 10.50" T/C) What I need to know is can I use a 157 tooth flexplate on a 351W? Can I retain the 351W's current harmonic balancer? Or do I have to get a new bellhousing/torque converter?
