ive got poly engine mounts with headers and cam, and i think it feels pretty close to stock and my exhaust never bangs. it did before, i pulled my old mounts out and they were seperating and in nearly two pieces. lol.

On the other hand, is there any risk/issue with just dealing with them hitting the floor?
Yes, and I'll be able to tell you hopefully soon. Just have to get starter, fans & radiator in and will know how the poly engine/trany mount help.

I just saw the marks where it did hit. But nothing major I could see happened from it.

same here, mine were torn up pretty bad. Either crap GM part or I was putting some serious torque on the ole engine

Both Engine mounts were in two pieces, trany definitely needed replacing.


btw: It was easier for me at least to just undo the cradle 4 bolts on each side, and then the engine mounts from the engine. seemed to us a ton easier than just trying to wiggle the mounts out of place and back in.
