I have a basically stock lt1 (except for a catback) with the 2.73s. I first ran a 15.2 at the track because I had some bad knock at high rpm. I fixed that and am going back to the track soon and just wanted to know what would be considered a good/typical time for a stock car with 2.73s. Thanks.

 

Right around 14.3 to 14 flat @ around 99 mph.

I got mine to go 13.7 @ 100 with nothing but a K&N air filter. It was almost perfect track condishions though.

 

13.6 with 60 degree weather, good track.

Had CAI, Catback, 160 stat, and manual fan switch.

I still attest that the fan switch helps a lot with LT1's.

I ran 14.2 with just catback and a hot engine a few months beforehand.

 

Man, you guys are quick. I only ran 14.4-14.5 @ 95 mph stock. I had to kick, scratch, punch, and crawl to run 14.0 and still didn't make 100.

 

I ran a 14.6 with just a cold air intake.. Car was hot though... Then i gutted my cat and did some programming along with 3:73 and run 13.8 with little traction... When i gutted my cat I dropped about .4 of a second.. Dont know the difference in weather conditions but it was faster went from 99-100 to 101-102.

 

There are a lot of factors that go into your time such as weather/altitude/etc.. But my car completely stock, including the factory paper air filter ran a 14.1 @ 98, I still have the 2.73's and have gotten a best 60' of 1.804 out of it, though I am hoping to get a new rear soon...

 

mine ran 14.43@97 when it was bone stock

 

mine ran 13.7's with just slp catback and CAI @ 100mph at sea level, I'd think the folks getting mid 14's or slower are either spinning like crazy or at a high altitude

 

A local guy ran 14.3@97 in a bone stock 95 formula, down to the paper filter, I tuned it with tuner cat and it resulted in 14.0@100.
