for starters, none of the cars will compare to the ls7. i’d guess a simple bolt on LT1 would walk away from the LS3 cars, only to get decimated by a stock c6z

subjective question. we don’t know your goals, feelings or anything else. all i got from that blurb about cars was you want more power. there are plenty of ways to get it. it doesn’t take much for a na LT1 to make a stockish ZL1 look silly.
