Prothane Motor Mounts 6-503-BL 351c ?

Recommended Posts

This has surely been debated a thousand times but, these fits the 351w, then they should fit the351c ?

If I add shims under the mounts they should fit right in the 73 ? I belive the 71-72 standard mounts fits if you raise them. Anyone who has done this ?




For knowing your limit you have to pass it ::thumb::

If your running headers dont get these, they need grinding to get them to fit.

Correct. However, I have these and the grinding needed is minor, which won't affect its functionality. I think these are great mounts of the captive type that work great for 71s.

Well to be fair mine was a 70 cougar with a 4V 351C, just figured they would close on all 351C. I had to hack 1/2 of an inch on mine. I ended up switching them to some premium stock types.
