I drive a 98 Camaro Z28, Auto, 3.23 gears, intake, exhaust, underdrive pulleys. I ran at the track bone stock and ran a 13.4 @ 103 mph. With my mods right now, I ran a 13.2 @ 105 mph. Sorry guys, my buddy has an M3 (Cosmos4) and there is no way you guys can beat an LS1 without some serious mods. Around the corners it's a different story, but in a straight line, forget it.
