385LT1 (scott) posts on here, not too often though i dont think. he has a cage and hit 11.40s on the old setup and street tires. i dont think youd want to hit it off with that car
scott's the guy to talk to about LT1s though. he has a company (abrino performance engineering) that will do whatever you want to your LT1 for good prices. you should check out his website/forum
www.abrinoperformanceengineering.com he's built quite a few sick LT1s
