What do you mean save my 10K motor, the LS9 cam is a stock GM cam, how in the hell would that ruin my engine! I have been around cars for a long time, and I know big cams need matching springs! Thats not what my question was guys

If I buy a aftermarket cam setup your talking ALOT MORE MONEY! Not to mention more money on a tune, and I dont want a tune yet! This cam works with stock tune and headers, ADM has already done this and sells this setup. The cam swap would be done by me, so its only a 200$ job for 20rwhp, why would you not do it!! You would rather spend $400 on a cold air...not me! That cam and long tubes will make some nice power and I will have money to spend on other areas of the car. Like make traction to put down the power!
