Very nice numbers! Good luck and welcome to the 408 family! Our trannies eat alot of power up, if you would have a 6sp-add another 30-40rwhp!

the motor was in a m6 before mine and made 509hp so it only lost about 20 hp from going in the auto so i can't be upset with only loosing that much

With a locked converter, an auto won't lose as much as people would think. Especially with a 10 bolt and 2.73 gears. What was the setup in the other car?

I just swapped cams but I made 500/470 with the same cam you had. I ran ti at the track last year but my TB was only opening 2/3 of the way. The throttle cable was in the wrong hole. It ran 11.0 @ 123 with a 1.52 60'. I had a 4L60e in it then with a 4000 stall. It shifted at 5700 on the 1-2 and the 2-3 since it wasn't at 100% open throttle.
