LS1 vs LT1, which is better?

[Chris 96 WS6]

Maybe we can start a good argument, which is what this forum is for :D

[1970judge]

considering ive built both it cost me more money to build an ls1. but dollar to dollar ls1 will make more power. spend 1k on an ls1 and 1k on an lt1 ls1 will beat it , however, an lt1 is like a general SBC so if (like it says) money is not limited lt1's will beat an ls1. My.02 and besides lt1 bodies look better.

[urbanhunter44]

Imo, once you get into modding, they're both great motors! Although the LT1 will ALWAYS sound better :)

[Vendetta]

LT1


Cheaper parts. Underdog status.

[F-Bobby]

i hear there is a lack of heads available for the LT-1 my friend is trying to find something aside from the standard LT-4 head. and ive seen what happens to an LS-1 when you put even the most basic boltons on the bitch. i vote LS-1, what other engine do you know that gains 50 hp by cleaning out the ashtray in the car? lol

[Vendetta]

People are making good power with ported stockers. Have him contact Eric Bradby or Lloyd Elliot. They do it for cheap.

[loudmouthzls1]

ls1 for cause it feels a lot smoother compared to the lt1's i drove

[chevy94c]

LT1 :rockon:

[Vendetta]

LT1 is t3h winning!!!

[1FASTBIRD]

I had a 97 SS LT1 and now I have 2000 WS6 LS1 and I have to say I love my LS1. I had the same amount of part's in both car's and my LS1 had a lot more power. :thumbsup:

[LS13RDGEN]

LS1 much easier to work on and responds well to mods. (well most of them do. :finger: )

[1970judge]

Ls1's respond great to mods, giving in the gods engine status but i have done so many tihngs to ls1's helped friends and when building my own engine i found that lt1's are easier to work on IMO.

[TheRoad64]

LS1 must win. All aluminum is just cool, plus the LT1 has opti, which makes it hated by me because I have had to replace one.

Dont see much arguing going on :dontknow:

[Vendetta]

The LS1 has a quicker E/T than the fastest stock suspended LT1, but the LT1 has a faster record trap speed than the fastest stock suspended LS1

[contraststriker]

LS1 much easier to work on

Both the LS1 and LT1 are half under the windshield...that doesn't sound easy to me!

Yeah unfortunately the LS1 is superior, but that makes sense since it's newer. I would sure hope GM didn't digress when creating a new vette motor :thumbsup: I dislike it when LS1 guys act like its total god compared to everything else though...the main advantage is only the better heads over the LT1, and no opti.

Ill take an iron block before id take an aluminum!

[Chris 96 WS6]

Ill take an iron block before id take an aluminum!

So true for ultra high HP applications. I think the LS1 responds better to basic mods just because the heads flow so dang well.

Keep in mind the LT4 head was designed with lessons learned from the LS1 development program.

[NICETRY]

Ill take an iron block before id take an aluminum!


stock for stock though, LT1 block vs. LS1 block, gimme LS1 all the way. All aluminum, 6-bolt mains, better oiling, etc.. It's a no-brainer.

[kevyn]

I have owned both. I liked the low end grunt that my LT1s had but the top end of the LS1 rules. Since I only mildly mod, I like the ls1. It's definately easier to work on too.

[Iroc313]

I like the LT1 cheap mods and the closest thing to the tpi

not knocking the TPI, as I used to own one, L98 89' IROC, and loved it, but............are you serious?????

or at least I thought It was sorry I'm not completly a genius when It comes to motors :o If thats what you mean

[Acid Phreak]

Give me an old school Gen I 350 with a carb. :p

[Iroc313]

werd, maybe not carb

[Acid Phreak]

Your right.. 2 carbs. :rockon:

[Iroc313]

lol :rockon:

[gettinthere]

LS1 hands down. It's gods engine.

[LiquidFire350]

i like both, and have both in my driveway, i have the LS1 and my dad has the LT1

hes got nothing more than C5 wheels and computer tuning from MadZ28.com and still runs in the 14s

ive got basic stuff, lid, cat-back, tb bypass, 160 stat, madz28 tuning, 3.23s and it ran 13.2

so mine faster but i still like driving his, you cant beat that sudden kick in the ass torque

[lt1 97 formula]

i have an lt1 and i have driven and rode in many ls1s. they are both great motors. the lt1 has that crazy bottom end torque and then the ls1 has the godlike top end so yes the ls1 is newer so its going to be better stock for stock but once you start seriously modding both engines its fairly even.

[Fastbird]

Each motor is great in it's own respect, and for the majority of the public the LS1 is going to be a better motor. Once you start REALLY digging into it, it's a coin flip as to which is better. Strength and durability of the LT1 with a slight disadvantage to power, or take the power advantages with possible longevity repurcussions with the LS1??

The LT1 owns all with a set of 18* or 15* heads on it though. It's not a true LT1 at that point anymore, but it's close enough. :D

[Darth Xed]

Straight from the factory, the LS1 is clearly superior in overall performance.

I have owned 1 LT1 (95 Corvette) and 2 LS1's... (99 Z28, 04 GTO).... so I have seat time in both. :)

And, in turn, I believe the LS2 to be greater than both the LT1 and LS1... (no seat time yet, though...)


One engine that's always overlooked is the one-year "bridge" engine... the 330hp LT4

[97m6formula]

This is probably gonna start some crap.. but to say LS1 is a god motor is completely ignorant...Sure you can throw just a lid cat back and a cam at a ls1 and put down 380rwhp.. In that respect it is better.. But that cam costs almost 400.00 I got a whole cam kit for my lt1 which included roller rockers, valve springs, timing chain, pushrods, gaskets for 658.00 and my car was trapping 114 on a mild cam..Then I sprayed a 100 shot at the 1/8th mile and was trapping 123.5 which is good for a low 11 so that was only 1200 invested.. I am by no means saying a LT1 is better but I gaurantee the majority that say LS1 is a god motor havent owned a lt1 or modded one...INcluding buying my car and modding it including suspension wheels and everything I spent 18k and I have a high 9sec street car almost 4k of that was just in my drivetrain..The ls1 is awesome if you are gonna do basics or a cam.. No doubt it will smoke a lt1 with the basic mods or a cam.. But once you get into strokers etc... You will spend less on the lt1 and be just as fast as a LS1... I havent seen it many times.. Ive owned two lt1 cars and one ls1 so I am also speaking from personal experience... Either way you cant go wrong but stock for stock a lt1 m6 will "feel faster" on the street than a m6 ls1 just because of the torque band... "No flaming intended im not that kind of guy"

[nostyta]

Never had an lt1 car, just my LS1 so my vote goes for the only logical choice for me.

[baddogz28]

Imo, once you get into modding, they're both great motors! Although the LT1 will ALWAYS sound better :)

If you heard my car, you'd shit your pants. :P

[LiquidFire350]

chris, i will steal your exhaust

[Lifeisgood]

both are great engines, and served there purpose.beating everything else.
but LT1's have passed there prime, and now the LS1/LS6 will to.
with the new LS2/LS7 engines, they will become god's engine

[SlowPurpleLT1]

well being an lt1 owner.. im gonna vote lt1... but if i had the chance to trade my lt1 for a ls1.... id probably do it... just so i wont have to hear about how slow lt1s are anymore

[sleeperSS]

i dont know what you people are talking about when they say that the LT1 is hard to work on..... hell an opti only takes an hour to change out. on that note, i'd even go as far as to say that the OPTI gets a bad rap. people spend alot of time changing them because of mis-diagnosis, and find out afterwards that that wasnt even the prolem. while meanwhile the LS1 has oil consumption and oil pump issues. i say there fairly even when heavily modded. i find most LS1 drivers have there head so far up their ass they couldent tell the difference anyway

+1

I work on both the LT1 and LS1/LS2, both seem pretty equal in difficulty.
I do like the shaft mount rockers on the LSx style heads, very easy to install, compaired to adjusting, turning motor to TDC of that rocker's cylinder you're working on, etc, of a traditional SBC/LT1. I also like the valley cover design of the LSx. Keeps the front and rear of the block clean, unlike our LT1's which you cant get to stop leaking for the life of ya. :mad:

[sleeperSS]

If you heard my car, you'd shit your pants. :Pgive the LT1 the same mods you have, and it will sound even better

[Phoenix57]

both the LT1 and LS1 are dead engines as far as production. the LS1 is simply a superior engine. the LT1 has major potential, but has issues(opti).

[Bawls]

So take the money you saved on the LT1, throw h/c package on it. $1800 from LE. add the delteq system $500-600.

Then get pissed because you still have stock manifolds, catback, injectors, tb, clutch/stall.

[baddogz28]

Preference is subjective.
And I was wondering, what makes one engine sound better than another?



Matt, what's my car sound like? :party:









BTW, if you want this exhaust, you better bring a torch, the duals are welded on. :banana:

Jumped on the bandwagon. :P

[contraststriker]

Yeah it is "jumped on the bandwagon" because LT1's aren't that inferior to LS1's. Fundamental difference is heads. Of course, that makes it just a little sweeter beating a cocky LS1 owner who thinks he's got God's motor. For the price of an LS1, you can buy an LT1, mod it, and beat the LS1.

What he said. If you think that there's not many modded LT1's out there, then keep thinking that. :P

[Nick@VictoryRacing]

If you had two factory long blocks and $2,500 to spend on each one the LS1 will make more power most every time. This is assuming the usuall mods, nothing done here that you wouldn't use for a daily driver. No Engine Master secrets at work.

Now take and make it an unlimited budget and my cash is with the elder statesman. Right now LS1 guys that are pushing 25-30# of boost and some even higher and looking to add additional head studs and ways to hold the head down.

So I suppose it depends on your goals really, but both LT1 and LS1 have tons of potential just waiting to be discovered.

[Chris 96 WS6]

I won't call it an unfair advantage but one thing the LS1 has the LT1 doesn't is aftermarket blocks....never enough LT1s out there IMO to warrant somebody casting hi-po aftermarket blocks....so every "LT1" out there setting records is running a factory block.

It would be nice to have stronger aftermarket iron and an aluminum option for LT1 guys.

[67RSSS]

Using the old ass dyno has proven to me that stock the LS1 (el es won) will kick an LT1 in the nadds then walk over and bitch slap it while it's down.

BTW: A RAT motor will walk over to both, slap em like they were Moe going off on Curly and Larry, and then bop their heads together for good measure.

[97m6formula]

i have an old inferior LT1 right here that hasjack s*** invested if somone wants to sit down...its a six speed though so its definetly slow

[NOSTYLS1]

Well a friend of mine has a 96 z28 383 sc lt1 and I still busted that ass at the bristol track. WE are both a4, he has a stall converter,I dont, and we both had M/T tire's. Oh yeah, he's got ALOT more money in his car than I do.
I still gotta give the lt1 respect, If I didnt ride in my friends 95 T/A [new at the time] when I was 16yrs I would have bought a mustang.

To his credit he didn't say he was going to race you. Maybe he just wants to kick your ass :lol:

[99formulam6]

well, i hope for his own sake he meant race me...he will still be beaten, but atleast he will be able to go home on his own power afterwords...

:box: lol

That's funny, since he ran a FULL SECOND quicker than you BEFORE he got the motor built... :lol: Who knows what he's running now.

that's a pretty bold statement coming from a lt1 guy...

Head to Chitown then and run him for a grand. You will come back with no ego, not to mention broke as hell. :roflmao: His car is no joke man. He will make your 12.4 second slug look like a school bus.

[99formulam6]

well, me going to chicago is just not going to happen. but if for some reason i do go, i will run him. regardless of what my sig says on how fast my car was, im still confident in my car/driving abilities, and it would be wise for him/anyone to be as well.

You guys are all e-badasses! Can I be cool too?

Wow, are you kidding me? Your confident in your driving skills vs. someone much faster than you? I live in Chesterfield, and by no means have a 12.4 second car. But I can't STAND LS1 guys sometimes. Funny how I beat a bunch of them at the track on the 23rd. I run a 13.4. I had a guy laugh at my car when I was in Chicago. He had a stock 99 SS. It was ALSO an auto. Guess what, I handed this guys ass to him and he wouldn't pull up next to me after that.

[Chris 96 WS6]

So can I ask where all the visitors are coming from? What site? There's 7 people reading this thread right this minute. I have to guess somebody posted a link somewhere.

Anyway, welcome yall, I hope you guys will stick around. Remember the "smack" forum shouldn't be taken seriously...its purposefully for these kinds of arguments :D

[99formulam6]

so b/c my sig says i ran 12.4, that makes it as fast as i can ever go? no. i made the sig a long time ago and just copied and pasted the code when i came over to this site.....so after the other mods i did, along with a tune, i can safely say im faster than that. so the only way to know who is faster is to race, but there is no way in hell im driving to chitown for a race. and, everyone knows anything can happen on the street, regardless of who is fastest at the track...

and bawls....you are cool :)

[99formulam6]

and since the sig is causing so much trouble, i edited it. and we will just have to see what it runs next season

[Bawls]

Two seconds faster? Cause that's what you're gonna need to be running to be in his ballpark now IMO.

Also, imo, you cannot use this remark:
and, everyone knows anything can happen on the street, regardless of who is fastest at the track...

while at the same time saying this:
so the only way to know who is faster is to race, but there is no way in hell im driving to chitown for a race.

You're picking on a faster car... if you aren't gonna challenge him to a race and put your money where your mouth is, you're gonna get owned internet strongarm style. The only we have to compare is numbers and setup if you don't race, and you are on the losing side.

[99formulam6]

but if there arent solid numbers on both sides to use for a comparison, then you cant compare shit.

yeah tha was just a cam and a small wet shot hittin at the halfway mark

[Enthusiast]

Okay you guys can argue all day about the ls1s and lt1s power, something the TPI is undoubtedly a little behind in. But you have to at least admit the TPI, even though it may not be the most powerful, it is one of the prettiest engines. Ahh maybe not, since what i consider pretty is a healthy dyno chart. JK

[CamTom12]

That was meant as a joke, sheesh.

I could care less what it is, I'm going to mod it until it's fast enough for me (never, lol)

Fully assembles the LS1 is close to 150# lighter. Over the front end, that makes a huge difference.
