Hey you all,

I'm looking for information on 4th Gen F-bodies. Specifically, I'm interested in the diff options, gearing differences (rear end and tranny), 1LE vs. base model specs, and any other differences from model year to model year.

For example, I know the '93s are speed density, not mass air. Are there any differences there from a performance or maintenance standpoint? The '93s also had a slightly different T-56 tranny, as I understand it. Were '93 and '94 models not available with 3.42 rear gears? Would a 150 mph speedo indicate that the car has 3.42's? No governor? I remember my old roommate's '94 T/A didn't have the "GT" package and as a result had the 115mph speedo, governor, and maybe even 3.23 gears (instead of 3.42s).

I know in '96 they went OBD-II with dual cats. They're also rated at an insignificant 10 hp more than the '93-'95 models. Of course, in '98 the LS1 came out with much more power. However, the LT1s are obviously still very compeitive in F-Stock, despite the power deficit, iron block, and smaller front brakes. Any particular reason for this? Or are the right people just not running LS1's? (IMG:http://www.frrax.com/rrforum/style_emoticons/default/unsure.gif)

So, needless to say, I'm intersted in LT1 vs. LS1 differences, too. But, I'll likely stay with the cheaper candidate, i.e. the LT1.

I should point out that I'd mainly be interested in F-Stock, so update/backdate concerns are of less importance. I'm not sure if/when I'd move to ESP.

Thanks in advance,
Tommy

My $.02:

I've had a couple LT1 Camaros, a '94 and a '95. I did quite a bit of F stock autocrossing back when I had them, and all I can really say for sure is that they were a blast to drive. I competed against LS1 Camaros many times, but can't really draw any conclusion on F Stock potential other than to say I didn't feel like I was at any real disadvantage to the LS1's.

I recently bought a 98 Camaro with the intention to do some autocrossing again. I did look around for LT1 cars, but with what I had to pay for one that was well maintained and in decent shape, I figured I might as well go for a newer LS1 car...this assuming I could get into a nice one for less than 10k, which I did. I'm prepping to ESP rules, but whether I was planning to run FS, ESP, or SM I'd have been just as happy with an LT1 car. If you find the right one you can save some money over an LS1 car. I think all the other pros and cons kind of equal out, so to me its nothing more than a question of money.
