351W engine HELP

Hey everyone I have 351w 420hp crate motor that doesn't have a balancer or fly wheel on it. My question is which ones do I need. Ive seen 28 and 50 oz. balancers.Maybe something I can tell from the crank???The motor is going on a aod auto trans. The guys that built the motor are no help. Thanks!!!!!

you have to find out whether the crank is internally balanced or not, that says which weight balancer you use. It may be the cam or crank, I always get those two confused.

Hey I was confused. I hadnt looked at the motor in a while. It has a balancer on it, but I was not sure which flywheel to get. There was a part # on it PRR1214FX4 if that helps. I was thinking of calling the local ford dealer if noone knows off the top of their head. Thanks!!!!
