All summer i have been planning on getting the MS3 but now i think it might be to big? i am going to probally be runnin stock heads and LS6 intake with 411's out back in either a 9" or 12 bolt still deciding.the car is a 2000 M6 and isnt a DD but gets driven a decent amount of time. is this cam too big? i want a nice size cam but not over kill. this is all i will be doing untill next winter. any imput will be great

 

Everyonew with the MS3 raves about it. Your setup seems fine for it.
If you have second thoughts, get the TSP Torquer II.

 

any more inputs?
