You are going to the dyno today right? Let us know what your numbers are ASAP and post the dynograph if you can. If you dont have a scanner or have no way of posting them, see if Candy will post it on here for you. Good luck man

Finally got her done! We strapped it down about 2:30 yesterday evening and made a couple of runs. Before he messed with it, we got a max power of 321.55 and max torque of 311.17. Pretty damn close for a street tune huh? Then Allen starts his magic. We experimented a while and ended up with a max power of 331.20 and max torque of 325.87. Not bad for a naturally aspirated 5.3, although I was hoping for more. The dyno runs were made with the short belt(which is worth 4hp), through the mufflers since I have no cut outs, and with 26" bfg drag radials. My tires were waaayyyy too bald and not rated for the speed. I also had him mess with a couple of other things for my personal satisfaction and everything has come out great so far. Big thanks go out to allen and the rest of the gang at Futral Motorsports. Hopefully if Candy see's this she'll post the dyno graph.

Great #'s also with the small cam.
Very nice! I am actually hoping to put down a little more than that since I did 300/305 a few weeks before my swap.
