My bad, I forgot to put that the NNBS doesn't count with the bigger intake manifold and the 799's.

Regardless, there are plenty of LM7's etc. that put out over 330hp with CAI, LT's, Cam, tune... im just trying to put all the proof in one thread, since i've seen you guys do it I know it can be done.

Ths argument would've been over before it even started if I had dyno'd my old truck. I know for a fact that it made over 330hp alone with the EPS cam i had.

I think your right. He also had the ls6 intake though not the stock truck intake

Is it that rare?! I know i've seen a lot of guys putting down some awesome numbers with cam, lts. Of course dyno's all read different numbers and everyone is tuned differently but I don't think that making 330+hp on a pre NNBS 5.3 is a rarity. I guess its just me
