I stand to be corrected 351C has motor mounts and bell housing pattern like a 302, 351W
should be the same 6 bolt pattern. Whichever flywheel you use it must match the balancer and the crank. Late model flywheels 157 Teeth (manual)
164T (auto). I think the bell housing to gearbox bolt patterns may also be the same
