I know one thing my OPTI does not suck! I wash my engine, drive in the rain, snow, ice, whatever, and I have noproblems. There may be a problem with the early OPTIs (92-94) , the OPTI was redesigned in 1995 to a vented system.

EVeryone says the L98 is better off the line, well here it is again, the timeslip between a stock LT1(just muffler eliminators) and a stock L98(a few little tweaks).
65 Z01(in the L98 can vouch for this slip.
4477 is me in my '95 six speed, 4842 is Jim in his '88 L98 automatic.
Now either the weather has a better effect on the LT1 or the LT1 is simply better, let the numbers speak.

Top-speed is another thing ... pro for the LT.

In all honesty, I never did understand the "which one is better" idea.
The truth of it is, they all have a role in the history of evolution.

Every single engine is a improvement over the previous engine.
The LT1 has reverse cooling- this is an engineering improvement
The LS1 has an improved spark system to fix the optispark problem with the LT1.
The LT1 is a superior engine to the L98 - it always will be and people in this board just need to deal with it and get over it.
The LS1 is a superior engine to the LT1 and will always be. This is the natural evolution of engineering.

you know how hard it is to find a good aftermarket head for an LT1? or where to buy/build a big stroker LT1? something more than 388 cid?hmmm....
seems to me L98 boys go faster/quicker in the long run

TFS and Edelbrock also make LTx heads.

65z01 was trapping 101 on that slip. That is a fast L98 no matter the year.

Admittedly, I've made a lot of refinements on mine over stock. Even the notorious plug wires aren't bad to R&R on mine now. I'd like to take an L98 completely apart and reassemble it to see how many things I could do much more intelligently than the factory way. I can look at it and see many areas that could be easily improved as was the case on mine. I think they're both great engines. I just enjoy working on LT1s more.

I think they run out of ideas on how to improve the latest models of the LsX series so they just went with more C.I., which is fine by me!!!
They may have went with more improvents but I am not sure on this.... I guess I need to read up on the C6 forum.

My basically bone stock 85 ran 11.3 @ 119.
I ‘m not sure if the 383 stroker made much of a difference, but other than the stroker and the superram and the AFR heads and the vigilante torque converter and skinnies and slicks it was bone stock right down to the paper filter… AND those times were run with a broken antenna too!
Now let's see a stock lt1 touch those times!

My '90 L98 runs low 13's on street tires without breaking the bank on mods. However, if I had my choice for the same $$, I'd go with the LT1. Better to start at 300hp than 250, unless your going to heavily modify it...then the L98 is a more user friendly platform.
