seriously, how many people on this board have stock cars? not many. who cares whos faster stock, of corse the ls1 is. BUT when you run into another camaro on the street or track i bet your not going to care whos car was faster when it rolled out of the show room, but whos car is faster w/ the mods you have.
yes stock for stock the ls1 is faster, its a better engine. but unless you are runing 9s then there is alwayse a lt1 out there that is faster then your ls1, and there is alwayse a ls1 that is faster then your lt1. its all who you are racing and what they have.
sure, with a couple of hundred in mods, you CAN have a fast ls1, but think about how much cheeper a lt1 is, and with the same budget how much more you can have to spend on motor work for your lt1. it all eventualy evens out.
in the end all that matters is that you have a sweet f-body, and its faster then your neighbors mustang lol of corse unless he cheats and buys one with a supercharger

 

They both can be made to be fast. Its all in what your willing to do to em. For some reason we(lt1 crowd) don't have anyone..well..very few willing to do to their cars what these "fastest" ls1 do. The fastest bolt on lt1 is SAR2k with a 11.9. This was in the 3400 lbs range too I believe. If he got as light as most of the fastest bolt on ls1s he would have been right with em. He dynoed 325 rwhp with a locked converter. Only about 20 rwhp from what a equally modded ls1 puts down. Same thing with cam only etc. etc. etc. The ls1 crowd just goes to more extrems with weight reduction etc. from what I can see.

Stock vs stock there is really no compairison. The ls1s are flat out better engines. I have both..the lt1 and my wife has a 99 ls1 formula ws6. Bone stock just like it came right off the showroom went 13.24 at 104. My car I was bairly able to get a 13.9 at 99 or something before I began the mods. They also have the advantage in cam only vs cam only. Their heads are not only 15 deg. but flow as good as alot of ported lt1 castings. They are better able to use a bigger cam because of this. There is way more to those heads than just the 15 deg. difference too. But..a well built heads/cam 355 agains a heads/cam ls1 should be a good race. I agree wtih fastfatboy on that. More lt1s should be in the 420 rwhp range. I really don't understand why they aren't. Shoot..in BR we had two stock bottom end lt1s in the above 440 rwhp range..one hit 450. One being from thunder racing and the other from futral motorsports. Joe O has turned out a few of these two I believe. When I'm tuned I should be in the high 460 rwhp through a 9" and 4.71 gears..and with a intake change to longer runner(like the ls1s have) I may be pushing 500 rwhp with a 355. Its all in how you build em guys. Pay attention to details and don't cut corners and you can have a ls1 eating lt1....its fun..come join us.

 

2 1/2" exhaust?!!? That's your damned problem. LOL Unchoke that car!

 

I love how the LS1 guys look down on the LT1 but then they claim that the LS2 is nothing special....how hypocritical. Old tech is old tech, either way you look at it, and the LS1 is in the same crowd as the LT1 now. OLD NEWS!!!

 

amen to that brother. check out this ram air on the zaino site. no 4th gen camaro will ever look this good. i love my camaro but i would trade it tomorrow for a sweet ws-6.
ram air with zaino

 

I hate to say it because im the Lt1 guy. But honistly, Gm stopped making the Lt1 for a reason, they made something BETTER. There is no way that an LS1 ir less of a motor in any way. The LS2 will do the same thing to the LS1. And i can't wait for that to happen. Just one more motor we have to stomp ricers with :]

 

here is another link i like. it was head flow data done by carcraft. scroll to the bottom of the article and there are multiple links. the lt1 stock flow info is in the smaller than 180 cc link. the ls1 stock flow is in the over 200 cc link. the ls1 head almost out flows the lt4 at .500 and does outflow it at .600. those ls1 heads are sick.

car craft head flow numbers

 

YES!!

 

Amen to that

 

Alright guys settle down

Here is how I see it....

An F-body is an F-body. I know SO many guys that are like hahaha you got an LT-1 the LS-1 is so much better...it's like are you joking....A LOT of LT-1 owners like the LS-1s as well, they just don't talk sh*t about them because they have no reason to. I don't treat F-bodies as an enemy, I see more of an adrenaline rush if I race one, because I KNOW it will be a great race. I love these cars, that's all there is to it. You're not an F-body owner unless you have an open mind about all of these cars, slower or not.

I had this guy in a 99 SS auto that sat there and scoffed at me in this parking lot at Blockbuster. He was like 35 maybe? He got on the road and I handed him his ***, but you don't see me going around and bragging that oh I beat an LS-1?! They are both great cars. And regardless if he is a bad driver, a win is a win, no ifs ands or buts about it. You red light at the strip, you lose, you miss a shift, you lose.

I don't even know what an LT-1 and LS-1 are, all I know is that it's a 350 5.7 V8 with a lot of horsepower, that's fine by me

 

Dunno if it the same one he was talking about...

Article from PHR: http://www.popularhotrodding.com/eng...e/0409em_gmpp/

In short...crate LS1, no accessories (used EWP), Hooker LTs...the STP (same as STD, I dunno) corrected numbers were:

429hp @ 5,600rpm...425tq @ 4,800rpm.


Take it however you want.

 

"That I can see" I thought he was refering to a completely stock LS1 accessories and all.

 

LT1 I agree that is average I am sure many LT1s have gone higher.
LS1 many I am sure have hit that range but on the average
I would say more like 280 to 300RWHP on an actual stock motor. I have heard people saying they are stock but have aftermarket cold air intake lid and computer tune.

 

I don't know about you but I am VERY disappointed with the track times I've heard from the LS2 goats. Maybe it's the extra weight and not being broken in but I was hoping for alot better times. I do however take my hat off to the LS6 and LS7 Vettes. Now that's impressive but also expensive.

LS1 WS6 looks better then any f-body with the only exception being first generation. So all you Camaro guys praising the looks of the LT1 Z28's can kiss the WS6 nostrils because as far as looks go, that hood owns joooooooo

J/K but they are mean as hell looking. Especially a freshly washed and waxed black one.

Power wise is no secret. Stock for stock LS1 wins. Bolt-on vs bolt-on LS1 wins. We can just skip right over cam only. Heads and cam vs heads and cam is where things really tighten up. But If I remember correctly a LS1 recently made 500 rwhp with full bolt-ons, heads and a rediculously large cam so even there the LS1 can be a slight favorite to win. But now we are down to FI and N20. This is where I believe the tables turn in favor of the LT1. Seems like the LT1 handles boost and N20 shots a tad better.

And in the ultimate end we have the LS1 with the quickest ET but the LT1 has the fastest trap. Pretty even playing field and in that sense I say LT1 = LS1 for ultimate potential.

Some LS1 guys need to get off thier high horse. But then again, so do some LT1 guys.

 

LT-1 MODS ARE CHEAPER! Beat that LS1 biach
