LT1 vs LS1 it's a question of torque

[kyleozzie]

EDIT: im done with this thread. Just realized I dont care whether a bolt on LS1 or bolt on LT1 is faster... you're still slow either way

haha good one

LT1 cars are more often abused, Joel got it right. Just look how many even exist on this site anymore. I just said 97 becasue is was a newer year with OBD2.

Nuh-uh, my (nearly stock) el-tee-juan is the fastest car on the planet!


J/K Comparing a stock LS1 to a stock LT1 is pretty pointless, IMO, because most people I know that own F-Bodies don't keep them stock for long. . . It's all about what you do with it, and a properly built LT1 can beat an LS1, and vice versa. They are pretty close as far as output goes, but stock for stock, the LS1 has the advantage. Combine the higher power output with the slight weight advantage. I'm happy with what I've got, I'm not out to beat the next guy, I'm just out to have a little fun.

Excellent now we have some input. But I'm not sure where anyone would get the idea that the 2 are closely matched and are even a drivers race. Like I said before I have a bit of experience in the stock vs stock aspect here.
Case in point, In 1998 I ran my stock 2,000+ mile LS1 M6 against my friends `96 20+K mile Camaro SS M6 (310HP). His only mods were K&N filter and 3.73's, my car was bone stock down to the AC air filter. He had his car about a year and knew it well, while I had mine for a couple months and was still getting used to it. We rolled off a light even in 1st gear and ran from about 10mph, we both had mild traction issues but I still proceeded to put close to a car length on him between shifts. So by the top of 3rd gear I was about 3 cars ahead when we let out of it. We were both in our late 20's, great friends and had both been into and built cars in the past. So we were not newby teens with no experience.
I believe this run is indicative of what can be expected from two relatively stock F-bodies using each engine and from my experience the run was fair since no advantage was given to either car.
And for those that want to claim BS or say that maybe I was picking on a slower or less powerful car I'll say this.
In 1998 the LS1 F-body was all new and nobody in my circle or on Gratiot Ave. for that matter new how fast these cars were. So we didn't know how the outcome would play out.

im not going to call BS on anything but one of the LS1s i beat with bolt ons was an automatic C5 and it was at 131 dragway. Not much for driver skill there.

Then we have Kyle/Ryan's 95 Z28 which doesnt even have headers and it has LS1s on its kill list.

Joel I totally agree with you.
Although most impromptu races that we have all done are run what ya brung, And in my experience someone in an auto/2.73 equipped car (even an LS) is at a serious disadvantage against a seasoned vet behind any 6 spd car.
As the saying goes assumption is the mother of all F -ups.

not sure what stock lt1's run but my car stock went 13.08

they dont run anywhere close to that. 13.7s maybe? Im not even sure. Jon's old 97 2.73 car ran 13.9s bone stock.

A long tube LT1 vs a long tube LS1 will be a closer race than stock to stock.

true. i dont waste time between gears. back when i had bolt ons and my synchros were fresh i could usually beat people up there. I think ive got another season or so in my trans before its going to really start slowing me down.

see I still have to disagree with you Joel, a LT1 vs LS1 race bone stock should always go to an LS1 car.That being said traction does play a huge factor on the street as does the starting speed/gearing but trap speed for the cars stock for stock should be a good indicator. It does happen all the time and I would say an auto LS car vs a well driven 6 speed LT1 would be a good roll race.

Valid points Jeff and I agree but it's been my experience that there are too many variables during a street race to assume the outcome esp when considring 2 cars that are somewhat closely matched as in a auto w/2.73's LS1 vs a M6 LT1.
As I said before assumption can be the mother of all F*** ups, because in a Drag race the more powerfull car is not always the winner. This is where experience has it's merits.

uh, pretty sure i said exactly that in one of my posts above.

LS1 cars were far enough ahead to consistently win, but i wouldnt say they arent close.

then there is the weight factor my ragtop weight was 3750 # on nascar scales with a half a tank of gas now the weight probly is around 4000 # with subframes and a tunnel brace so if your car weight was 3500# mine 4000# there is 500# if you are a 150 # driver I was at 300# now its 650# low tank of gas to a full tank your over 700#

Can't believe those camaro's had 2:73 gearing... were those the only gearing options in those years?

ya that was a gearing option in the autos. manuals only came with 3.42
