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

Expect eventual problems with optisparks, diffs, and to an extent power steering pumps.

My recommendations. Take FWIW and call Sam too, DO NOT use Mobil 1, and keep the oil level topped off.

Expect an FS car to weigh mid 3,400's. In general the Camaros are lighter than Firebirds.
No weight saving advantage to an LS1. I've seen Jr's and Sam's car put on a scale when they were both FS.


As far as ESP the LT4 is definately the best choice. I'll tell you right now though, that there are no more. Try buying an LT4 longblock.......

You need more than a 4bolt block for an LT4 conversion. ALOT of parts are required. In fact almost every part is a little different.

In extremely rare instances where someone finds a complete LT4, or finds all the parts necessary, all NEW ESP LT4 cars are illegal.
