hey guys whats the differance?
i seen on gmmg's site that they come with 380 hp so what do they do to them to raise the power?
all i seen for mods are exhaust and a lid.
thats what my car has for mods plus a rear suspention that set up for the strip.
can some one explain it to me

LS1W66

380 HP Blackbirds are supposed to have Air lid, Catback, extrude honed exhaust manifolds, 3.73's and a custom tune.

Negative on the 3.73's: http://gmmginc.net/programs/Blackbird/. You guys should be pretty even, the 380 HP is a BHP rating, meaning its not at the wheels. You should be around the same power, however if he is a 6-speed you may be in for some trouble since your auto is stock, he will put more to the tires than you. Also, 98 heads and the LS1 intake kinda suck, but it should still be close.
