ok i have a 02 c5 ls1 with a maggie blower, cam, nitrous, well im wanting more but i cant put anymore boost to it an be safe, so im gonna forge it... doing a little search im finding that for a forged 346 from texas speed is the same as a 383, any ideas an what i should do, i really want to do the 383 but not sure on if it would be a pain or not.. im wanting to keep the ls1 block an just re sleeve it for the 383 , anyone done this yet? BTW i was looking at the callies forged roating parts.

thanks in advance Jason
