ahh this is somewhat true the times you are looking at were with my 5.3 with stock heads, i haven't been to the track yet with this setup, true the cam should be smaller for me but i bet you my 150 shot puts down more hp with this cam then it would with the smaller cam and that's my goal i built this motor to run better on nitrous then on motor which it hit like a mofo last night, and my drivability is great TRT Performance did a bad ass job on the tune, and i am in the 11's without a doubt in my mind
