HRMMMM.. those numbers seem VERY low to me.. with that cam and those heads this should be another 550 RWHP car.. i made comparable numbers with my lil ole patriot stage 3's and a stock LS6 manifold and with less compression.
whats the deal with all these low dynoing ET headed cars?

Through an unlocked automatic, those numbers look strong. Probably difficult to estimate what the motor would do with a manual transmission, but I would expect that it would be anywhere from 30-50 rwhp higher. Good numbers!

You don't know race cars then.That graph shows the converter slipping the whole run 
The car is not for dynoing but it is for racing.I bet the car will screw

Congrats dude.. mine is comming together very quickly too. Mine is VERY simalr to yours LME 408 11.85:1 , Same cam as yours, Same ported Vic, But i went with the TFS 225 heads... might make a good comparison between the two heads..
difference would be my headers are 1 3/4 stepped to 1 7/8th, im running power steering still, i dont have the electric water pump, im using an intake elbow and a nick williams 90mm TB, im running a 4l60 with a 4k TC... plus i dont have any one to tune it.. ill have to figure that one out i guess.
