i will get some graphs and a short video

450rwhp

Around 450ish whp, but only because the TH400 & 8.8 are going to 'eat' horsepower.

480rwhp

ok you guys wernt to far off.i just finished the final tune and made 460whp 473whtq.i will post a sheet up later. this was done on a dyno-mite dyno.i am not sure if they read a lil different than dyno jet or not.

Cool, I have a very similar Fox build going except using a smaller cam and non ported heads. Please post up when you get it to the track, I'm more interested in some MPH and ET's

With all that compression and ls3 heads with a healthy cam I would expect more.

before the tune the car run a best of 6.55@107 w 1.44 60 in the 1/8.no 1/4 yet
and it made 403whp and 379 tq on the first dyno pull.

With a 5000 converter, you cannot rely on a dyno but for tuning. Numbers mean jack.

one of the interesting features on a lot of dyno's that gets overlooked is the acceleration log. it doesn't do much to compare 1 dyno shop to another but for multiple runs on 1 dyno it will tell a lot. you may have a 450hp motor that takes x seconds to go from 4500 to 7500 where I have a 450hp motor that takes y to do the same thing. it will tell you a lot about what's going to happen at the track.
