NJ guy here, was wondering which one it was

 

MTI Stealth II, we've had several stock headed (LS6) 400+rwhp cars using the stealth II camshaft and it will pass smog.

 

I agree, the MTI Stealth II is a great cam that improves power and torque in all areas of the RPM band without sacrificing driveability or low end power. The Stealth II rivals the power output of much larger cams and maintains stocklike driveability, idle quality, and emissions. In fact I have a brand new MTI Stealth II cam and cam kit for sale.
