Default 1/4 mile time

well i took my 94 Camaro Z28 A4 to the track two weeks ago and ran my car for the first time at Sacramento Raceway. I ran a 13.8 @ 101 MPH. It was about 80 degrees outside. I want to know what everyone elsa has ran with there LT1's almost stock or even modded. Here are the mods i have done to my car when i ran at the track.

Pacesetter mid length headers
Magnaflow 3" high flow cat
3" 40 series Flowmaster Cat back
TB coolant Bypass
Air Foil
LT4 Knock Module
Ram Air with Functional SS hood (K&N air Filter)
A4 with 2.73 gears

Agreed.
2.73's just suck, and the stock Stall is nothing to be proud of.
Get a CAI, Full 3" Exhaust, Better Stall and Atleast 3.42's, and you will see low 13's.
SFC's, better shocks and Coils make a big difference too.
