This is a timeslip for my best of three passes I've put on the car to date of a 12.79 @ 109.24mph. Based on mph, I'm sure 12.50's are well within reach.

:thumbsup: sweet ride, it definitely takes great pics - i think your right that 12.50's are well within reach - bet it sounds mean as hell too with long tube headers and the exhaust setup you got - with heads, nice aggressive cam and throttle body (don't forget a nice custom tune) your going to reach your numbers for your timeslip no problem - thanks for sharing the pics with us, have any sound vids of the exhaust you can share also :thumbsup::alien::rockon:
