Not bad for a 5.3 and 22s but a bit disappointing when you compare this dyno sheet to a 6.2 dyno sheet. Don't get me wrong the 351hp 320tq is respectable but cam headers and the work to be swapping lifters and the money alone for all these mods I would rather find me a used 6.2 and swap it out and make the same numbers with a stock motor and still have all the potential to make more power.

Oh yeah don't get me wrong I have seen the potential of a bolt on 5.3 and I think it's badass that your putting those kind of numbers and improving on GMs most common engine. Alot of people won't go through the trouble to swap a motor or just can't and are left with the 5.3 to work with. Thus going the route you guys are taking and spend money to make that motor perform... I was just saying my opinion in what route I would take givin the same amount of work and funds. You guys are doing great don't let what I said take anything away from that.

We are figuring about a 40 hp gain on just the cam to the wheels. As for grinds i can do just about what ever you have in mind all i have to do is call a custom grind is really no more than a off shelf grind...
