I have a 1985 351W out of a F250 4 speed manual truck. Is the balbnce on this motor 28oz or 50oz? I was told it was a 50oz motor but Im not so sure. I thought all 351W were 28oz motors. Does anyone know for sure? Its a 164 tooth 11 inch clutch. Im switching motors with my dad and giving him my 302 and was going to use the stock 351W flywheel on the 302 if it was the same imbalance. Thanks
