to my knowledge... no. however, i know of an ls1 thats going into an e36. :D
if i were to go with a 350, itd have to be an ls1. lt1 honestly cant compare and the ls6 is too rare. if you were to swap in an ls1, you could supercharge it and do some other little tinkerings for under $10k in parts and then youre making ~600hp and ~700tq. sounds like the smart thing to do if you REALLY want good bang per buck. btw, a 600hp&tq supercharged 5.7l chevy v8 would be about 10x more streetable/daily driveable than a 600hp&tq turboed 2jz.
