Heres the bottom line.
L98 needs major mods to run with a LT1 but parts are cheaper.
LT1 needs major mods to run with a LS1 but parts are cheaper.
LS1 is awesome out of the box and with mods its downright scary.
I beat LS1s but I have lots of mods.
I sold an 88 IROC 350 to buy my LT1. I had minor mods on my IROC and it still was never close to hangin with my LT1 stock.
If I had my IROC back I would throw in a carbed 355 and then it would run 12s.
In my opinion its not worth messing with the TPI induction, naturally aspirated it just won,t breath well enough up top to be worth anything.

The LT1's reverse flow cooling is a far better design then standard flow. As far as not being able to get bubbles out, there are bleeder screws that you use to bleed the system, and once its done, you have no trouble with bubbles at all. I am also very amused by the amazing timeslips that people are getting around here. Of course track times on the internet, well, are like fish stories. The point is this, stock for stock an l98 is just not up to the lt1's level. I love the l98, i own one, however that does not change the fact that the lt1 is far more superior. As far as bang for the buck goes, yes an lt1 costs more then a l98, but you have more right out of the box, secondly to get a nice low mile iroc, formula, gta, etc, you are going to pay about the same as you would pay for an lt1 with about the same miles. Also, lt1 cars have rack and pinion steering, nicer interiors, mostly plastic body panels so they dont rust to the ground, etc. In closing, you can go out, buy a 95 m6 z28 with around 75k on it for 5 grand or so (not saying you get leather, bose, etc) spend 2600 bucks for the lt4 conversion kit , and be putting 425 ponies plus to the crank, and not even have 8 grand in the car, now thats bang for the buck

I guess i may just be biased because i have seen so few Ls1 with ANY decent mods.
i.e. An "air lid" is NOT a mod.
Can anyone link up some nicely modified LS1 cars? I'm serious, i'd love to see someone do it right. I think the motor does have some great potential, although i am much more skeptical than most to deem it the "best ever."

Right now my 88 bird with a beefed up L98 and an overdrive tranny is sitting in front of tiny 2.73 gears. I'm sure it'd top out at like 150+ at about 5500 rpm.
But when i put in some better gears, well that'll drop to like 125 or 135 (i'm aiming at 3.73s.)
Overall, though i'd say the LT/LS motors are better at higher rpms/speeds. I believe the redline in an LS1 car is 5900, correct?
It's right about 5400 in an L98.

An L98 in NO WAY pulls as hard as an LS1 from 4500-6000RPM. Yes, the L98 redlines only 500RPM before an LS1, but the LS1 is pulling almost just as hard at 5800 as it was at 4500, whereas the L98 is just dying once it gets to 4500.
A torque curve would make it really easy to see.

For the amount of money you had in your WS6 (including the car), you could have a 12 second L98 car easy IMO.

It would have taken a lot more money to buy a brand new 92 Z28 and mod it to that level. I think I came out ahead.
Or just buy a TTA and put less than $100 in mods and run 13.0. Been there on that one also.

But you must admit that the differences lie only in the intake type setup (i.e. cam, manifold, head) which can be easily modified on the L98.
In fact, i'm in the process of modding an LT1 intake to fit my L98 motor.
But i agree more with Rippin...the pricetag on your CAR was by far more than an L98 car, even though the motor itself is getting cheaper.

My car wasn't that much more than what a 92 Z28/Trans Am was going for. The later LS1 WS6 cars were much more expensive than the LT1 WS6 cars.

My old WS6 is way down the list on the LT1 side.

I thought this thread was about L98 vs. LT1? Seems that it has changed to an L98 bashing thread.

11.78 & 113.75 Best ET and MPH w/ 1.58 60'
This one has stock manifolds.., stock heads and cam. Only a lid, filter, stall conver, tranny work, slicks, and a good driver.
Check out www.ws6zxr.com and go to Tulsa Firbird and Camaro Club and you can look through and see many nicely modded ls1's easily in the 12's with an a4, lid, filter, and exhaust.
Also.. the Lid IS a mod. I saw a 2000 SS 6-speed pull 300rwhp, add a aftermarkit lid and filter.. and pull 319rwhp. Everything else was stock.
I watched a 02 WS6 with lid, filter, and LT headers pull 356rwhp.
Here is a more modded Ls1:
1998 Red Camaro SS: MN6, 18x9 & 10-inch Enkie V1 wheels, Cartek Stage II head/cam/intake package on rebuilt 346-cube short-block, 451 rwhp & 408 ft-lbs. of torque on pump gas, Stealth torque arm & control arms, Strange 12-bolt w/4.10 gears. New combo w/26x11.5x16 ET Streets, front skinnies and 3620lb. curb weight: 1.60 60-FTs., 11.20 ETs and better than 122+ MPHs. Daily Driven and fully loaded.
The biggest thing is these cars still maintain 25-30mpg on the highway.

No one is bashing the L98 that I can see.
Most of the opinions stated here are true, sorry if that hurts.
I love the looks of the third gens, I have said this before, I think they are the best looking of all the camaros (except the 69) and as I said, I would love to have my 88 IROC back but the TPI would have to go in favor of a more powerful motor.
We are talking dated technology here, I mean the TPI setup came out while I was starting high school, the advances since then are leaps and bounds over what the TPI has to offer.
Its still respectable but just does not have the ability to hang with later model engines, but then again what older motor does?
