Actually I was at the track when LS1JAY ran his car. It was a great day at the track. As far as I know it was stock. I have the car that went 12.2s on stock RSA tires. The mods are:
Whisper lid
Amsoild filter
!Throttle body
!MAF
Mac headers with offroad Y-pipe
Cutout
MidWest 3200 converter.
My car started out as the slowest one any of us had seen at the track. I ran the car once with it bonestock at the track. My best for the day was 13.80 @ 100.80. The car ran extremely rich from the factory. It seems my car was one of the first 99s built and we think it may have the larger 98 injectors in it. As I leaned the car out it picked up faster than other cars with similar mods. Also I think fordmanck was at the track also.
