motor should be fine with boost, but your trans/rear end wont...the rear end stock is already under stress with the stock lt1 power...it just needs to be beefed up a bit. My friend has one and the trans doesn't like to handle the abuse, he just had to get a rebuild(Auto trans as well), and he put a few upgraded parts in it in the process it likes to break loose going in 2nd now with the stock motor.
