Default Fastest (mostly) stock LT1 ive ever seen

I sold my old 94 when i bought my 01 and i saw the guy up at the track tonight. All the car has done to it, is and after market CAI otherwise Completely stock 94 M6 formula. He ran 13.77 @ 100.62. On street tires, and everything. I may just not see alot but i thought that was crazy. Just thought you LT1 guys would like to know your cars stock can run 13's EZ. When i had mine i thought a Low 14 would be fast.

My friend had a white 97 formula automatic with 2:73's and just a flowmaster muffler and he ran 13.60 ish @ 101. The first time he did it at the track no one could believe it ! He backed up the numbers on more than one occasion, so I know it was not a fluke.

My 94 ran 13.6 with a Mac catback and K&N CAI. Added LT headers and went 13.4. There was an Ed Wright tune on it.

Totally stock besides Mobil 1, new Goodyear 245/50 GTII's (stock wheels), and K&N Filter.
13.89 @ 99

It had a better pass in it too, I just wanted to see where I stood.

a friend of mine went 12.700 @ 107.96 on a 1.779 sixty in his 96 T/A vert. full weight with no jack and spare was something near 3600lbs. a generic mail-order tune, mechanical water pump, on 3 yr old drag radials, mid length headers into an ORY into a borla cat back. almost 100K miles on the motor.

his name is j0n over on NJFBOA. dont know what his name is over here, might be the same.

my 94 with 100k miles went 13.57 with a cold air, gutted cat, and 3.73's. And that was hitting the factory speed limiter before the quarter because the speed limiter was set at 108 from the factory and the speedometer was off because of the gears
