Is it possible to use the same flywheel on a Ford 351 Winsor and a 351
Modified as well as the starter???? Please help!! The van is a 1978 E-150
with a 351 Winsor (I was told) and the replacement transmission
(C_6)supposeably came out of 1987. When I bought the new flywheel the bolt
hole patterns where different leading we to believe the motor was actually
a 351 Modified. I'm confused, think you can help me?
