I spoke with a mechanic today that said that he has a modified LT-1 that he had built for his MC PS. He said it puts out 400+ hp and looks really nice. He originally bought the MC with a bad engine and went to the junkyard and replaced the block with one from an impalla SS. He kept the boat for three years and never had a problem with it. In the mean time, he built this other LT-1 and it has been sitting covered up in his shop. He said if I ever had to replace my engine that he had one for me to the tune of about $2200. I should see him this weekend at the local boat show and will ask him more about it then. Just thought that was interesting, and if anyone is looking for a nice clean engine he has one.
