I'm putting down 373 with everything you got - fast intake, ud pulley, and a cam. I would think depending on how aggresive your cam is you should be putting probably close to 430+ idk about the quarter mile time I'm curious about mine as well..

Dude your only putting down 373 with your mods in a LS2?????? Im putting down 393/380 with my mods in sig with stock heads and intake!!!! Were you dyno'd on a dynojet or mustang dyno???? What size cam do you have???? The dyno I was tuned on is not generous by anymeans, if anything its a tad conservative..... Im just curious....

I think you misread it. I said he has everything i have minus the fast intake, underdrive pulley, and a cam. I just have boltons, the ones in my sig and i put down 373..

I will guess around 505 rwhp and 480 rwtq. Should be a beast. My friend has a trex cam only 04 gto and on a 100 shot he runs 11.4 @ 121 mph at our crappy track. I think you will run low 11's around 125 mph if your track is near sea level.

hp: 460+
tq: don't have a clue

the cam seems a little small for a 408. i'm using a 236/240 .615/.610 112 cam in a 416, and my setup is considered "mild".

SHould definately see high 400s, low 500s on the HP side and I'd say mid to low 11's at the track.

Mid to high 400's (450 to 490) with decent torque through the mid range.
The stall will eat some of the power and the cam is kinda small for a 408.
With it tuned properly it should make for a great daily driver.
