I love a nice LS1. There's something to be said about being able to produce that much raw HP from a block. My friend had an 97 LS1 Firebird with a few bolt-ons that made good HP and I've seen a few single turbo LS1's. They were the only real street cars that I've seen that could hang with us single turbo Supra's.
