Yup! I laid down 380? On a mustang dyno on my L99 with kooks 1 7/8 headers flowmaster cb and Vararam intake and a tune of course.
If I were him I'd get the heads off replace them with the replacement lifters (all are Ls7's) to get rid of those damn AFM lifters because I just don't trust them that's , especially under boost. Then Get a set of ARP head (bolts) not studs. Get a set of stock length chromoly pushrods. A whipple or a Kenny bell supercharger, a set of kooks (or whatever brand you choose) 1 7/8 headers I don't recommend cats with a blower because they have been known to blow out and cause BS issues. You can keep your stock exhaust and if its not loud enough for you or want a different sound then just getting a catback of your choice.
Lifters = 115
Pushrods = 100
Arp head bolts = 130
Blower = up to you on the brand and your research, I like kenne bell and whipple in that order
Headers = up to you and what your budget allows.
Tune and install is all on a quote from a reputable Lsx installer and dealer.
The cam can wait and see if he still wants MOOOOORE POWA.
Just my .2
