Thanks to everyone for their help. I am asking questions on behalf of my brother and nephew. They don't have internet access. They have a 1972 351W that they want to swap into a 1998 4.6 mustang with a blown motor. Ive ben told they will need a 5.0 bellhousing. Can anyone advise me on motor mounts and will the FI system from a 4.6 work on a 351W. As you can see I know nothing about Mustangs besides when I was a teen my best friend had the sweetest little 67 fastback. Had some great times in that car. I'm sure I will be asking more dumb questions so please don't forget me. Thanks again!
u will need mounts off a 5.0 that goes in the 94-95 mustang, its the same sn95 style the 98 is but was offered with the pushrod. u may also have to change the k member because they are slightly different. again, u can get one from a 94-95 or even the 94-98 v6 would work.
