There is a difference between 454 and 350 or small block fo sho..

Cant say on the diesel.

Misinformation at its best...:shaking:

350 - 454 engine mounts for pickups in the 73-87 year range should all be the same as far as bolt patterns, dimensions ect. And someone correct me if I am wrong, but the 6.2 should use the same mounts too.

When I swapped out my 350 for my 454, I used the smallblock mounts that were in the truck on my 454.
Direct bolt in.
