LOL at the guy who said Mustangs are running with Z06's. Even A Cobra won't touch a stock Z06. high 11's low 12's with the handling of a car that cost 4 times as much, from the showroom floor. The 02- 03 Z06s are trapping from 116-119mph, that's crazy, nothing done to them and they aren't even made for drag racing....

I just can't see how a stock L98 will beat a stock LT1? I've driven an L98 C4 with LT headers, CAI, chip, exhaust, MSD ignition, basically pretty much a full bolt on car. It felt pretty much as quick as my LT1. The owner told me he ran a 13.7 in it, he weighs like 300lbs though. So I guess 13.5-13.6. With those mods an LT1 is pushin 300RWHP give or take a little. Low 13's, maybe high 12's on a bolt on car. They pull strong up top too, just the LS1 pulls a little stronger. In the end they're all quick but I can't see the argument between stock cars though.

 

Stock L-98 cars runs maybe 3-4 tenths in the 1/4 slower.

Put headers cat back and cold air on both cars and really see the Lt1 pull on an L-98.. The Lt1 heads flow around 30 cfm more stock. The Lt1's exhaust restriction does not take full advantage of this. Lt1.s hava a full 360 degrees of timing also and a tad more compresion stock . And the intakes on these cars are awesome.

With Full exhaust and cold air I dynoed 298 RWHP on my Lt1. It also ran 13.01@109 with just those mods on a 3680 car with my fat *** driving. No L-98 can come close to this with just those mods.

The L98 is lacking ove teh LT1, just like the LT1 is lacking over the LS1

 

Revtime: Why the heck would you say it takes "major mods" for an LT1 to hang with an LS1? With boltons you can run 13.0's possibly 12's in an lt1. I don't call full exhaust, cold air and throttlebody "major mods".

I've come to the conclusion that some of you people really don't understand motors or how they work...

***And Thank you StealthElephant for correcting me. Yes, i meant the Cobra stang (NOT the GT) which is now able to compete with the Z06. My mistake.

Amean94TA:

C'mon dude, calm yourself. A) This is a casual discussion not a rant B) when my "L98" car is back on the road it WILL eat your Lt1, hands down. That's not a gloat, a rant or an attack, but a simple fact of how i built it.

I am not smoking anything. I know very well what i am talking about and it seems you do not. Have you ever SEEN the inside of a motor before? When's the last time you built one? I don't get it...the LT1 is AGAIN not the ultimate motor. It's a smallblock with good heads. Good motor, yes, but not fantastic. Just chill with it. You can build any motor to be just as good if not better.

Rippin:

the thirdgens do NOT handle better than the fourths. Although, with EXTREMELY simple mods, they can. Some better springs and shocks/struts all around and with some SFCs i personally think you'll see tighter turning and better response than you will with a fourth with same mods. But stock to stock, not gonna happen.

 

I would take any speed density system with a tunnel ram design.

I already have plans for my next motor, I haven't even driven my new 350 yet and I know it's not going to be fast enough to please me.

An LS1 swap is too much extra work, if I bought a TPI I would have to switch the intake setup. I doubt I could find a complete 350 TPI cheaper then an LT1 complete that would justify dishing out more money for a Stealth Ram or similar intake just to get the kind of performance the LT1 gives you out of the box.

Over the next 2 years I'm going to collet parts, a complete LT1, forge the bottom end, and put on an ATI Procharger kit hopefully by the time I graduate college (3-4 years). I have access to LT1 programming software and I'm helping someone with a Turbo LT1 swap into a 62 vette.

The 350 SD TPI doesn't interest me because it would be more cost effective to just get a complete LT1. The LS1 swap doesn't interest me because of the extra work to make it fit.

I think it's about working with what you have. If you have a 350 TPI, it's dumb to go out and buy an LT1, just change the intake and build the L98. I think with 90 posts we've realized that LS1>LT1>L98 in stock form. After that its more about using what you have and cost effectiveness for your situation. That being said, if I had a choice between an L98 or LT1 car, both in the exact same condition, not taking into account the fact that I am a 3rd gen owner and I might choose for that reason, I would take the LT1 all things being equal because it's got a head start from a performance standpoint, that only withstanding if I had the option of both cars, same price, same condition, basing my choise on on which engine would be easiest to mod. Thats not the case though, what you have is what you have. Someone has an LT1, there is no reason to go through all the cost of an LS1 swap, an LT1 can be modded to go as fast as needed and you already have one.

 

well said. I agree.

The fact stands that people just seem to think that the L98 is a worthless dinosaur, and that it not the case. That's basically my whole argument.

 

At the track there have been stock early LT1's that ran 14.20s/14.30s and I know of L98s that did that or better stock, so lets not make the LT1 out to be some kind of incredible thing, especially that the L98 never had a 5-Speed to compare to the M5 LT1s. (they are a few tenths slower) And as for handling, there has not been a stock 4th yet that got .92Gs on a skidpad (that's stock IROC numbers not even 1LE) or handle as tight or as good with such ease. (although they do have a slightly rougher ride) This is like common knowledge. Take a look and see which cars dominate SCCA F-Stock, talk to those guys and see who the better handlers are right out of the factory. The 4ths front suspension is set up for compliance rather than all-out handling, they aren't as low, and even turning the wheel, especially during "fun" driving, is more difficult than a Third. I've driven L98 IROCs, Z28s, and an 02 35th SS with all the SLP stuff, so I can make a real comparison. And also the L98 has that instant loads of TQ feel where the LT1/LS1 winds up then "hits" you instead and I happen to like the other better.

 

IZ28:

You really think that 3rds handle better than the fourth? That interesting, becuase i've always thought so, but i felt that my ideas might be biased becuase the front suspension in the fourths is supposed to be tighter, and i've only driven a fourthgen on select occasions. For some reason, albeit the fact that my car weighs a friken ton, it feel like it hugs the road much better.

 

It's true. It takes mods to a 4th to get up there with the Thirds. Also, 4ths are not lighter, it's the other way around. And I do not know how a 1LE Third Gen could weigh more than a 4th Gen, a regular Third almost always weighs less than a 4th. Just for example, an unoptioned/base 87 IROC L98 weighs 3,341 Lbs and a 305 TPI M5 is 3,250 Lbs. 4th Gens are the 2nd heaviest Gen and don't weigh in that low, more like 3,500 Lbs or more when optioned, it would take alot for a Third Gen Camaro to get around there. Firebirds are the heavy Thirds, more closer to 4ths.

 

even the cobra fall's way short of a zo6 so it does not matter you said gt instead of cobra and dude have i seen the inside of a motor....when was the last time .....look at my sig retread krs is my family's buisness and i build them for people like you that build paper motors.....................you said you will eat me hands down. when? and where? you just put your foot in your mouth. i will drive the whole way to you for this chance to show you that your car aint as good as you think it is by far so how did you build it or should i say how did you write your wish list that you cant afford. what are the specs mister i can build motors beter than someone that does it for 8-12 hrs a day for the last 6 years and i am 23 just so you know but its on so you know i wont let you live this down you said you will beat me now you have to prove it do you want to take em to a track or just down the main street in your town anytime anywhere for me i dont care get back to me if your a man and can back up that mouth

 

fyi smokey yunick designed the reverse cool on the lt1

 

i honestly still CANNOT understand how anyone can think that the l98 is better or faster....the law of physics just don't back it up, GM won't back it up, and i sure don't back it up because i have owned both and raced both and the results are always the same.....lt1 is the FASTER one, the only problem is why we hear of different numbers on the track is very simple, some guy from california would race his iroc and does mid 14's in quarter mile, then you get another guy for example close to where i live in canada, where it is colder and you automatically get much better numbers with a similar car, we all know our cars run much faster in colder weather ( you know, colder air going in), so you get better numbers in a colder climate vs + 40 .....the only fair way of doing it is to race both cars in the same city, same climate, same everything, now if you do that then ill bet you the LT1 is gonna be victorious in every way....from 0 to 240 kph. weather, altitude will always effect the way our cars run, but i sure beat every l98 i have raced this summer with my auto, and yeah we were on the same street, not in a different continent.

 

I do.
I have a heavily modded car, the LT1 is internally stock but anyone who sees or hears my car knows there are lots of mods on it.
I can beat most stock LS1s and hang with mildly modded ones, I have way too much money in my mods to call it lightly modded.
I have seen LT1s with CAI, exhaust, and a gear and they won,t beat an LS1 in the quarter.
Some have done it I,m sure but it don,t happen on a regular basis.

 

I've raced a ton of TPI Third Gens and only 1 beat me. But then again, he had the Vortech Head / Intake w/ the LT4 hotcam and some other goodies. He was dynoing at around 375hp. He didn't hand me my *** from the get-go, but he did beat me by a good car length in the end. I have a ton of respect for the TPI motors, they are good engines and can be made pretty quick. I think they have more of a visual appeal as well, those runners look awesome! I'm putting a Vortech equipped 350 TPI in my 1980 Z28, to give it a little pep! I don't hate on TPI's, they are awesome motors and the Camaro's and Firebird's they come in are gorgeous!
