If I remove a 302(60's or 70's) and want to install a 351(same vintage) what can I expect to cause me problems? Mounts? Flywheel/flexplate? Exhaust manifolds? General clearances? It is coming out of an early Bronco donor and going into an early Bronco receipiant. Any information would be great, I just don't know that much about Ford interchanges. Thanks.
