i went 13.24 at 104.20 with almost the same combo(stock cam)and an AOD -cobra intake, 65mm tb,73mm mass air, shorty headers,2 1/2in h-pipe and catback, electric fan, 2600rpm stall, and 3.73s. The main reason why it went so fast is cause it was great off the line even with street tires. My suspension consisted of eibach drag launch kit, steeda upper and lower control arms, subframes, and lakewood shocks and struts. My 60ft times were in the 1.8s and the car hooked everytime. Ice on the intake also helps
