For indymanjoe my suspension is basically stock but with aftermarket rear upper and lower control arms. I run 275/60/15 mickey thompson et street radials. 3.73 12bolt posi. My best run so far at sturgis(1/8 mile)track was an 8.01 @ 89mph. Both videos are 1/8 mile runs. The one with the trans am is a coworker of mine who called me out for the last night of "street night". His car runs a nasty lsx454,but just couldn't figure out how to race with it. We ran 4 times and he was consistantly 1 to 1.5 seconds slower than my "old" goat. He was sure braggin it up at work how he was gonna beat me and the GTO, but I guess better luck next year Brad. Have only ran her at the 1/4 mile track once and had massive wheelspin trouble, it was the opening day of the season and guess track prep was poor. Best run with limited traction was 13.01 @ 103mph. The car has a fairly mild .035 over 455,rollercam and valvetrain,cnc ported edlebrock performerRPM heads,ross forged pistons on manely rods on stock crank. All port matched and balanced.850 race demon carb on edlebrock performer RPM intake, hooker supercomp headers into 3in exhaust/flowmaster 40 series mufflers. TH400 trans with shift kit, 3200 stall convertor, modified govenor to upshift at 5800rpm.
