600hp isn't out of the question. I put down 620 with my 6.0 at 10psi. Granted I was running methanol, but also **** for timing cause of bad plugs.

 

sure thing, specs on the cam im not too sure but the last time i called the shop they told me it was the 401 comp cam with the VVT i can double check when i go to drop it off all i have is a VVT cam, 1 3/4'' long tubes from pacesetter, 3'' y-pipe, 3 1/2'' dual exhaust with flowmaster super 44s, 160* thermal stat, new comp push rods, springs, retainers, valve locks, stock rocker arms, K&N cold air intake, tuned by sam with 93oct, and tuned tranny and ended up with 422rwhp and 417rwtq im asking them to print out a dyno sheet again of their records and will post it up fastest time in the 1/8 was an 8.42 and fastest 1/4 was a 12.78 and slowest so for was a 13.22 having problems on the tranny hitting 2nd

 

620??? really good numbers is that with stock bottom end? i really would like 620 to 650 but dont wanna blow chit up lol

 

Yeah, stock bottom end. LS engines are tough.

For some reason that screen name didn't meet the standards of the site so I had to use what it is now. Lol.

So since I am in Dallas I call dibs on your old exhaust system!
