3.23 Dilemma I noticed while looking for some help in the Chilton's manual. The codes they have suggest that 1993 6 speed cars were only offered with the 3.23 rear end. Found this by accident, but I was under the impression that 6 speed cars were 3.42's from the first run, and the autos had the choice of 2.73 and 3.23. What other major deviations aside from the lack of a MAF and and 22 lb injectors are there?
Yep you are correct....The 93 F-Body cars came with the 3.23 gears in the rear end, but the Transmission had a steeper first gear than the 94-97 6 speed transmissions. Which was another reason they had the lower gears. However when they went to the 94-97 they had to use higher gears to compensate for the loss of the steep first gear. I'm sure you know that other than the 93 having a 3.23 gear setup, it also had speed density setup instead of a MAF setup, 22 LB injectors, required you to burn a chip for tunin rather than reflashing the PCM, It had a different fuel injection setup (Different intake(no crossover for the fuel rail in the intake manifold), it also had the fuel pressure regulator on the passenger side other than on the drivers side rear of intake, the writings/numbers on the instrument panel was yellow instead of white like the 94-97 cars, and the wiring harness was slightly different as well to run the speed density setup. I also know you can drop a 93 LT1 into a 90-92 Third Gen and use the same wiring harness and computer and just replace or reburn a chip for the LT1 setup....... But other than that I'm not too sure on everything else that is different. Besides the opti and timing covers and etc...

I never knew that about the '93 M6, I can see why they stopped doing it though, put a modded LT-1 M6 with 3.23 in the wrong hands and that would be the high speed chase from hell

how do you know or think this, you should be able to do it with any lt or is the opti on the 93 different then the 94, 95+ or are you talking about doing the distributer conversion

The 93s opti is just a regular non vented, nonspecific to the model year. How ever the 93s in fact had two six speeds the M29 which came with 3.23s and a M28 which came with the 2.73s, no Trans Ams got the M28, all six speed Trans Ams were M29 cars for the 93 model year.
Dont mean to hijack but does anyone know how to tell if you have 3.23's or 3.42's? I know there is something you can do like jacking up the rear end marking the wheel and manully turn the driveshaft but I dont know how this works. Also I know if you get up to a certian cruise speed and check the RPM's but again I dont know.

Correct Bizzzatch:
And as far as the 93 LT1 into a Third Gen car.....You CAN use any year LT1 engine, but you'll have to use the speed Density setup to install it in the 3rd gen and to make it pretty much a bolt in application.... Therefore the fuel lines- (or you can modifiy the 3rd gen setup to use a braided line setup), Also the Fuel Rails, Injectors, FPR, Intake Manifold, And all of the top end accesories for the emissions if your keeping the emissions and etc... Thats what I was refering to.
And the opti is just a non vented opti which was different from the vented ones... Thats what I was talking about there. If anyone else knows something I Don't- fill us in. This is actually kinda interesting to talk about. Although I'm sure there is info in the sticky's about this already.

I dont have accses to that paticular glovebox. I put the rear end out of a 96 formula into my 97 RS Camaro.
