If it doesn't make north of 640 RWHP at 11.3:1 cr or higher and pump gas....it was built by a monkey.
There's a dozen or so C6 Z06's (427ci) around here with 610-628 RWHP with ported heads, ported intakes, cammed, full exhaust, and a tune........
454ci WILL stomp those numbers if its built by a human, and not by a primate.....
.....oh...you're gonna really need 2" LT headers to get the most out of it.
