What does it take to make an lt1 to keep up with an ls1?
I dont know that much about camaros but I wanna learn more about them.

Yes I drive a rustang;)

Don't take this to heart because I'm not an expert either, I'm just getting ready to pick up a new Camaro myself. Two of my friends were arguing about this (both own 4th Gen Camaros or T/A's) and finally agreed on this. They felt that the LT1 will keep up relatively well with the LS1 in the 1/4 mile, just lagging behind a little. Supposedly the LS1 really shines in the top end compared to the LT1. I had a buddy that had a LT1 Trans Am with LS1 heades, some headers, and I think some intake and injector work and he was nipping at the heels of some SS's and WS6's on more than one occasion. Hope that helped somewhat.

To set a few things straight. Your friend must have meant he has LT4 heads on his LT1, it is impossible to put an LS1 head on an LT1, the bolt holes, water passages, intake ports and bore spacing will not line up. Generally an LS1 is about a second faster in the 1/4, that translates into roughly 8-10 car lengths, not exactly keeping up IMO. LT1's are good engines and respond well to mods, but the LS1 is simply a newer, more advanced design and will make more power mod for mod.

What would it take for an LT1 to keep up? I have a LT1 with Edelbrock heads and cam, cat back, cold air kit and all the other goodies and I went against a 98-2000 Camaro SS and it seemed like it was over before it started. We were at about 70mph on the freeway and he had me from the start. I fugured I'd give him a good run but that was not to be. I was impressed by the power he had. Not sure if he had any mods. (i hope he did!)

As said above the LS1 will destroy a LT1 in every field going stock for stock. With runners list of mods he should be right about on or a near stock LS1 in the quarter some where in the low 13s. However on the highway the LS1 is going to have a large advantage in the higher RPM range where the LT1 will start dropping off in top end the LS1 keeps pulling. I expect with your mods RUNNER you should be in the Mid 13 correct very close to stock LS1 times.

Now none of you LT1 guys take offense you know i love the LT1's too ;).

the ls1 is a superior motor but the lt1 has alot of potential. ive gone real low 13s on a bolt on lt1 with street tires. if you want a 12s street car then the lt1 is a good engine just takes a bit more to get it there. most ppl prefer the ls1 or switch to the ls1 wen buildin a racecar ive decided to stick wit the lt1 cuz i feel i can get my goal easily with a lt1 stroker motor (9.90s). but after that satisfies me ill be savin for an ls motor since i just watched a cam only ls1 go 10.76 which is very impressive.

obviously the ls1 is a better motor overall...its newer and has more advanced design...but you can make both of them run ridiculously well. and i'd think runner SHOULD be faster than mid 13's with a head and cam package...but i've heard edelbrock isn't the best choice. no offense runner, you know you're my lt1 buddy

When talking about a head/cam package there is a lot to take into consideration. There can be huge difference in power and times depending on the set up. If he was going all out with "go big or go home" he might be a little faster. But with his mods and say a mild to light street cam he should be some where in the mid 13s. Tires, gears, and a good clutch/stall would put him in the 12s with his mods no problem with room to spare.

This thread is from 07....Just saying... :P

I guess I'll throw my .02 in anyway; it'll add to my post count. ;)

Edelbrock is definitely not the best you can get.

To get an lt1 to stick with an ls1: full bolt-ons (LT back, CAI, gears (if you consider them a bolt-on)), stall/clutch, sticky tires, tune, weight loss, and a real good driver mod. This'll keep you with him until the quarter.

To be sure you're gonna beat him, add a cam into the mix and you've got a stock ls1 beater. :P

<<<mid 13's without heads or a cam...

<<<- low 13s without cam or gears i could hang with the ls cars

you should be getting mid to high 13's stock outa lt1 car.

i was runnin 13.8 completely stock on street tires in my lt1

mid 13's is pushin' it. A 13.8 isn't too insane though. Got any videos for us? :)

i would buuuuttt wen i tried to download te videos the camera needed to be plugged in and i couldnt find the charger so i plugged a random plug in and fried the $500 video camera so the best i could do is a cell phone video?

<<<<<< 13.3 lid only with 2.2 60'


and yes..... cbr.... were u paying attention to when runner posted that? [&:]

if i'm not in the deep 12's with my heads and cam i will be upset

Its all one big blur at this point :D. I have heard of stock LT1s running high 13s but never seen one in person. Back in the day when the cars where brand new they where running a little faster but now most have a few good miles on them. 13.8 is a great time for a 15 year old engine that has probably been around the block a time or too. Good run by the way ;)

<<<13.4 on motor, with crappy traction, and a 1.8 60'

keep in mind that different altitudes will drastically effect ET

as do track prep, track design, and track specifics. not long ago someone posted a video of his bolton only mustang GT running deep 12s or something. but from the angle of the camera it was obvious that the track ran downhill like a sonofab****. Not hard to shave a second off your time when you're cruisin down the side of a mountain :eek:

Or if it's the drag strip closest to me, racing on the side of an overly tall mountain...

Highest track in the NHRA, you see how your car likes it up here...:eek:

you also have a stall, lol. no offense or anything.. just saying, stalls on autos can make a pretty nice difference.

Basically, to answer the original question.. What does it take to beat an LS1 with an LT1?
The answer is, an act of God. Which is most likely not covered by your warranty or insurance..

Jk guys, I agree with everyone that says the LT1 is a great engine, because it is.. It definately does have potential, its just a matter of stock for stock, the LS1 is faster. I've seen "fast" LT1's and "slow" LS1's. It really depends on all kinds of factors, like spec and whammer already said..

all I was saying is that track times arent that meaninful....

the 04 mustang GT is considered a 14 flat car, but mid 14s arent out of the question in the track sucks. a 13.9 isnt unheard of either. the lt1 is also 14 flat, but a little faster than the mustang. but low 14s are usually expected, with a dip into the 13s being considered "good". while 13 flat is what is quoted for ls1s, mids are more likely. we get into trouble when we look at people getting in the lower spectrum for one car and the higher for another....

like that firebird board that i cant post at anymore :eek:, 13.8 for the ls1, 14.0 for the lt1 and that was that.
the world doesnt contain enough :eek:-faces to express my feelings about that board.

Wow! I forgot about that. :P

Do you remember what site that was? If you're blocked I'd be willing to go in and see how they're doing. You know, find out where they stand on the lt1/ls1 issue. :P

dont listen to specter he has a ls1 so of course he is biased plus he got banned at a firebird board
