I went with the Hot Rod Cams, which did not impress me untill I had them dialed in better with a custom tune. I gained 19HP on the dyno and lost no torque. While it was not a big HP gain what I saw was lasting HP through the RPM curve. Stock cams started loosing HP at 5300RPM With the HR cams it didn't start to drop off until 6600 RPM. It is making 320HP with the cams, delete plates, and a CAI, High flow cats and X pipe. They have hit almost 350 HP on a car like mine but with long tube headers.
