Mine has run 10.70's a few times and usually runs 10.80's on average days. In fact it ran 10.76 one of the first times out and I have made no changed to it since 2011 which is why it still runs the same. I just wanted to hit 10's in full street trim just as I drive it through the full exh on 92 pump usually but I have even had 87 pump in it when by mistake I put 87 in it. Still ran fine with no ping. Its a mild 440/493 that I can drive anywhere. I use Indy EZ heads and a Dwayne Porter solid flat tappet cam that's 264 & 270 @ .050 with .585 & .592 lift on a 110 LSA. Its 10.6 comp and I run the Indy dual plane intake with a Holley 850 DP. I have never uncapped the car and never had race gas in it. Its a 727 auto with a Dynamic 9.5 street/strip converter and I love driving it.The car body is all stock and all steel other then the glass hood. No tubs and no springs moved any. Ron
