my motor is a factory freak.. i had long tube headers, K&N intake, electric water pump, and a crazy ass tuned computer.. and some secrets and the car went 12.55@111 on drag radials.. and trust me it wasnt because im a good driver.. it did that time with a 1.86 60 ft time.. i put 313/340 to the ground with a failing optispark.. pm me for more info
