there is also alot in the tuning.... i mean yours made SAE Corrected: 415 RWHP / 378 RWT
and thats withh an ls6 intake and who knows what other stuff... it even has the 241's for heads i bet right but me with a ls1 factory intake and bolt ons and the worst flowing heads "806" casting..... made 395/381 on a slipping clutch your car made great power and yes it mad more on a smaller cam.... but this cam doesnt wake up till you get heads.... then compare them... the ms4 will make more power than yours with a set of heads that will allow this cam to breath
