Depends on the model, transmission, and weight of the particular car. Also depends on your track/traction and the weather conditions

Lighter cars are the Z28/SS and Formula. Trans Ams and convertibles are heavier (Trans Am +80, convertibles +180).

Figure mid 13s for an average LS1 with an average driver. In excellent weather low 13s no problem. On a crappy track, high 13s or even low 14s if there isn't any traction.

Overall, I'd say 13.4 range is about average for a stock 98 LS1.

I ran a 14.0 in the 1/4 mile with the mod's in my sig. But I think it had to do with the weather and track. I had good traction also and I am better than average driver.

I went 12.98@108.8 in a 99 Trans Am, 6 speed in less than ideal conditions with 3500 miles on the clock. I could have done even better but I bogged the launch.

I have a lid and catback on a 2000 M6 Z28 and spun like hell to a 14.006 @ 105.68 on a pretty hot night. That was very first night at the track - 60k miles. FYI, 60 foots balewww 2.28s

I ran mid 13's stock in a Trans Am A4 w/3.23 gears. The local track wasn't prepping very well last year. Most every late model LS1 F-body that was stock was running mid to high 13's there last year.

how big of a difference is there between having 2.73's and 3.23's?

Also, how do we ,know which one we have? I've been thinking forever I had the 3.23's, but now I see that the 2.73's are just as common.

-all m6 cars are 3.42
-autos are either 2.73 or 3.23, there is a code on the door that refers to the gears. But unfortunatly I dont know what they are. 3.23 was an option for the auto's, but most of them came with 2.73

I'm accessing the attic here, but I'm pretty sure it's the GU5 vs. GU2 code.

Wasn't trying to hijack the thread here GM_GUY. I'll post the question back out in the forum.
