There was a bit of a difference in the mounting of the 6.2/454 on original GM mounts. All other engines (I believe) used the bolt holes on the "corners" of the mount, (I think only 3 bolts though) where the 6.2/454 used one in the center on bottom. I am not at home at the moment to look at my frames, to verify. SOME, but not all of the aftermarket motor mounts will have 3 holes in the bottom.
Everything else should be the same.
