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

You'll get all kinds of info here, most of it's even good (unlike a lot of places!).

Maybe I missed it, but is this for F-stock? I assume so because of the "race on the cheap" idea.

My take. Buy either one, both can win. LS1's have more HP, LT1's have better torque belowabout 3500 rpm than a LEGAL F-stock LS1 does. And because of the gearing, you will at times be down there (well, maybe not in Texas....). Karen's right, the brake-hop issue doesn't rear it's head in an LT1 either, and it's cheaper to buy. Of course it's more ragged out, and if you get a '99+ LS1 you need not worry about limited slips wearing out like you do on '98 and earlier cars so that's a Pro in the LS1 column.

I'd not recommend a '93. The gearing is a non-issue because those cars all had 3.23's even with a 6-speed where the later cars have 3.42's with 6-speeds. Also the fact it's a one year only car causes some glitches, like the front brakes are different and that sucks when it comes time for pads.

What you wanna know??? I got lots of opinions. But in the end, frankly it's 6 of one, and a half-dozen of the other. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)

Edit: I'll add I think the reason LT1 steering feels/is faster is two reasons. The steering wheel is smaller which helps quicken it some. And the LS1's have a version of Magnasteer, which is pretty numb and might be slower too, don't know that for sure, but I doubt it.
