nice car! and ive seen 408's make 530-550 with some real heads on them but nice #'s for the heads you have. and i see you seem to have relocated your iat sensor?? if so that was a good call.. that aluminum gets HOT

yea was going to run the ls7 maf and got the harness but decided to just run SD and just used the ls7 maf and harness to plug in the iat sensor. Yea if i had afr, tfs, or trick flow and ported the 102 im sure i would make more power, Not to mention it was 100* plus when it was on the dyno some cooler weather and ill pick up some more. Over all im happy

My 402 makes very similar numbers with tfs 215cc heads and a 239/243 cam. 506/466 to be exact. What size headers do you have my tuner said I would pick up some decent power by getting 1 7/8 headers and 3" exhaust.
