I have a 93 GT vert. I run a 100 wet shot, timing dropped back to 10* and no probs. The hyper pistons aren't the horrible pieces of junk that some people think that they are. If you try to run it right to the ragged edge then yeah you might have some probs. But if you have a conservative tune and don't try to squeeze every ounce of power out of it you'll be fine.
My first pass with my 100 shot I got lined up next to a Camaro SS. I was a little slow coming off the line but when she hit 3k I drove it right around him. You should have seen the look on his face when we got back to the staging lanes. He lost to a pretty much full weight AOD GT vert. He wasn't really pleased but that is part of the fun.
