I did a couple of simple things to the car,,,,,shorty headers and an adjustable fuel pressure regulator,,,,bumped fuel pressure to 48 lbs. (where it ran the best) and the car ran consistent 13.90's spinning at 99 mph, with crappy 2.1 and 2.2 60 foot times.
It had more potential,,,but the darn thing was already going faster than my wifes bone stock 97 6 speed LT1 :shrug: and it took very little to get it there.
I would have loved to try more rear gear in the car, but someone made me a stupid offer and I let it go,,,,I miss that car.
Just to add for comparison,,,as I already mentioned it was a tad quicker than my wifes current LT1 6-speed,,,,,It was damn near running with my bone stock 02 SS camaro as well,,,an automatic car with 3.23 gears,,,,and it's best time when stock was only a 13.70 at 102 mph. When you think about it the tuned port L98 cars weren't too far off the pace,,,,at least mine wasn't :)
