New guy from Michigan

Here are some pics. The car is very solid except for the roof as you can see in the pics. It is very thin in spots so I need to figure out a way to fix it. If I just welded in patches it would be hard due to how thin it is. My buddy gave me a 5.3 that was swapped out because it was running rough but after he had it out we found a broken valve spring. I figured I would run an LS6 cam and valve springs, f body intake and a GM Musclecar oil pan. Only issue is i'm not sure which mounting plates to use since most don't mention anything about Pontiacs and I haven't figured out it the Pontiac 400 and a sbc had the same mounts.
