Since the ls3 is not native to this vehicle, it requires the expected fabrication to make it work. After-market ls3 motor mounts did not work without modifying the exhaust manifold - which I did not want to do. I did not want to buy a crate engine just to modify it. So, I had to come up with another way to do my motor mounts. I used the original mounts and modified them with a brace. The pictures don't show it, but I welded a piece of angle iron to the inside surface of the angle bracket I created, to give it additional strength against torque forces. As I said in an earlier post, I lack complete confidence in the strength of these to withstand this engine, but a car builder I trust thinks they are more than enough. Time will tell, as it will with many things I have done.
