RE:LT1 4th Gen VS L98 3rd Gen
#31
I don't know how this thread got started. But I do know I've read a bunch of c*** and some good things here. I had a 91 Z-28 with the dual cats. That car was incredibly quick until I got to around 110. My 95 Formula is incredibly quick all the way to 135+. I'm talkiing about quick for a stock car because that's all either ever was. And no, I never had either one to the track, just some street races. I missed my 91 and were it not for the divorce I'd still have it. Some of the ego trips here are a hoot! Are you guys having an F-body vs. mustang war here???? Because that's what it sounds like. I consider the LS1 motor far superior to my Lt1 and the same for the L-98. They're all great chevy motors and the trend does continue to get better in engine, engine management, tranny ect.

in my town there was a kid that had a 88 or 89 iroc auto with headers, exhaust, cold air, heads ported by a local racer and some other free mods and i saw him race a kid with a 96 Z28 A4 with only a borla. If anything i would say the kid with the iroc could drive better. I saw them race 3 times. The LT1 won every time. The closest the iroc ever kept it was the fender of the LT1. That makes the LT1 king in my book when it comes to stock performance. It won over a fairly modded L98 and was almost bone stock. I do realize when it comes to aftermarket parts you guys have us beat but from the factory we got better engines. Just like the LS1 is better than us LT1 guys.

You can't go by something like that. You'd have to know each car inside out and the driving ability of each driver. And proof that the IROC is a 350 even, whether it has 2.77s or not, and is in at least as good running condition as the other car and tuned correctly. A G92 L98 with all that should not have a problem with a stock LT1, especially when the L98 can take LT1s for a while and even LS1s for a few secs without any mods. Something is definetly not right there. Sounds to me like the LT1 owner isn't telling something or the IROC owner doesn't know what he's doing.

Wow, what a thread.
All I have to say is with my L98, I have no problem staying with the LT1's on the street. Out of the hole is where I gain all my ground.
But at the 1/4 track, they pull on me uptop due to the TPI not breathing well.
Only mod is a 3" flowmaster catback. The car also has a 9 bolt 2.77 posi rear.

It's easy to get confused when seeing a modded TPI get handed it's a$$ from a near stock LT1. The thing you don't consider is that over half of the modded cars on the street have "Bad Combo's". They might sound like a "bat outta he!!" an be actually slower than a "properly" set up STOCK car. (TPI,LT1,LS1etc)
I've seen it time and time again...Then the wrong impressions stick in peoples minds and they won't hear the contrary....
For example:
I raced a "Blown" LT1 at the track a year ago. (Kilkare Raceway ,a Yellow'95? Z with Yellow wheels,nice guy..)I expected to get my doors blown off!!! But to my suprise I took him outta the hole and he didn't catch me until 3/4 track where he passed me with a trail of black fuel smoke.
Obviously he had some problems, even if I didn't see any smoke I've known something was wrong...But to the agerage observer, they couldv'e got the impression that my car was just a BEAST or LT1's suck...true??
Use some wisdom with you judgements.....

Just my 2 cents....
As far as L98 vs. LT1:
In my recent search for a new vehicle, I test drove many LT1 T/A's, one even being a 97 Ram Air Trans Am....
They didn't feel any faster that the L98 at all. I was sorely dissappointed in the acceleration of the cars. It seemed like the L98 would run all over them...
Granted, I was not at a track, I wasn't pushing anything to the limits... but still...
The LS1 on the other hand.... that is a fantastic motor! The LS1 is the only reason I bought the '99. The 'bird is now officially my "project car"...

i just got back from slp day at englishtown nj. seemed to me that all the 4th gens out ran the most of the thrids with little mods while i did see a 4th gen z28 run 2 tenths of a second in front of my 305 15.6 to 15.4 i think a 350 woulda whooped him but thier ya go track results 350 l98 and a 350 lti are almost the same just respond better to mods

I really don't understand how you guys are figuring low end has that much of an advantage for you. Don't get me wrong, we all love low end power, but what, are you driving around on drag radials?!?! When my LT1 was stock I couldn't get traction on the street. It would spin all the way through first gear and some into second. I guess what I'm trying to say is, I don't see how low end torque is an advantage unless you can put it to the ground.

Does anybody have a dyno sheet of a stock 350 TPI?
I'd like to compare it to a stock LT1 dyno sheet. That would show which is really the torque king.
LT1 0-60 was 5.x throughout its run. TPI was 6.x. Still trying to see where the TPI is king 0-60??

All this TPI vs. LT1 stuff is fine and dandy. How about a little V6 action Now that is 0-60 King

But I was being serious. The TTA was pretty quick 0-60.
Here's the Pontiac numbers, mine was probably right there if not a little better. I ran 13.0 with a K&N, thermostat, and chip.
