1/4mi who wins?

 

I say the ls1 by a car length. I have some friends that have ls1's and they always beat my friends lt1 1995 vette.

 

only thing helping the LT there is the 3:73's

 

What he said ^..

 

Wanted to do gears but didnt wanna go 3.73's cause I like to take hwy trips. 2.73's kick *** for that purpose maybe 3.42's would give me the best of both worlds?

 

I have 3.73's just haven't got them put in yet. but idk about the 3.42's i'd say if u were gonna go with them might as well just get 3.73's

 

if you don't mind turning damn near 3k rpm on the highway, get 3.73's. i turn 2300rpm with 3.23's in my auto LT1.

btw, if the LT1 hooks, the LS1 is gonna be playing "catch-up" the whole 1/4. he's gonna be ripping through 2nd well before you even shift out of 1st.

if he hooks, LT1 by maybe 1/2 a car. if not, it's in the bag for the LS1.

 

im doin 65 at 2000 rpms with 323s and im goin for 373 gears to see what happens before i go with the 12 bolt. just got to get them in. are you sure the converter is locking up on yours?

 

2300 @ 75mph. 2k @ 65mph lol. probably should have specified

 

the ls1 still has a pretty good advanage in hp. should have him in the 1/8th then its all driver and hole shot both leave good you lose. get heads, intake, cam and headers with the 373s then you should win easy. 342 is a good middle for the a4.
