Thats very stout man, you should be proud of yourself.

500 should be in the bag with some tweaks. I'd love to see what TQ you make once it's finally tweaked out.

Holy crap!! I strapped the car down again today and made a few minor adjustments to the tune and put down 494rwhp and 460rwtq! The first few pulls the car was putting down the same numbers as before. I was just about to call it quits but decided to add 2* timing. We made one pass and it put down 482. That was the highest all night, so we made another pass. 4 passes in a row, all with out even shutting the car down, picked up 4-5 hp each pass until I got to 494. The first pass the ECT was around 170, the last pass around 190. I guess my car feels most comfortable around 190! I'll scan a graph tomorrow. Again, this is through 5.3 heads, stock LS6 intake, and 93 pump gas! Full belt etc...

Very nice!! I hope to get to the magic 500HP number soon. I'm running less compression 11.1:1 also my cam has less duration but more lift @ 631 on a 114CL. I'm also running 59cc ported LS6 heads. Good luck in getting to 500HP!!

Very nice I am impressed. I have a 395 and only made 489 and 472 tq. My tq was better but I have the Fast set-up. I am working on retuning the car and as I see what you have made I have hope.
