Hi Linda. Auto Transmission, 2.85 blower drive, heat blanket under blower, larger injectors, exhaust system mufflers changed, demon copy wheels, catch can, tuned for 98 octane fuel, all done by previous owner, he told me he pulled a 10.06 down the standing quarter. Certainly got some get up and go. Need eyes in the back of your head here if ya go faster than posted limits, the police fine you with very little tolerance for speeding
