Is this true I know that 93 cars had alot of differences then any newer ones, such as the t-56 manual trans options. My car has the more desirable m29 option, with shorter gears. I have been told this made this particular f-body the fastest of all stock f-bodys. Obviously it wouldn't be as fast as the special editions, but over the standered z28/zz or formula/trans am. Can anyone that knows for sure chime in.

Of course they are faster, duh!
JK, lol.
It is too close to tell if any year is faster...LT1s are not the most precision made engines, and GMHTP noted that through there testing over the years they found that even among the same years different stock engines can dyno up to a 30hp difference.
That is a HUGE range.

A 4L60 (no E) is a 700R4. GM just changed the designation for 1993. The '93 F-Body unit has different valve body, spacer plate, and lock-up wiring than any previous 700R4, though. The reverse input housing is also specific to 1993.
The 93 is speed density (used air temp and pressure to make A/F calculations) It does not have a MAF.
The 93 uses non-heated oxygen sensors. 94+ use heated models to reach closed loop faster.
93s had dot-matrix pattern tint on the ttops
93s and 94s use a non-vented opti, which can lead to O3 buildup and premature failure.
The opti is driven by a spline instead of a pin, the cam has to be set up accordingly.
93-95 had cams ground to 202/207 on 116LSA
96-97 had 200/207 on 117LSA
.... plenty of other differences, but like Shbox said ... nothing massive.

I've posted info in these threads too many times that I'm just not going to bother anymore lol No, the 93 isn't the fasted F-Body It is snappy, but not the fastest by a long shot. However, I do know you implied the fastest LT1 F-Body, and it's possible but it's all down to a drivers race. I think the 2 things that help the 93s out over the rest is the intake manifold having no fuel rail hump inside and the batch fire. Batch isn't really a good way to do injection when you want something that'll utilize the fuel efficiently, but it'll give you a bit more power I think. And I literally mean a bit heh I only feel that due to the added gas having some time to evaporate while it's waiting for the valve to open again, when another shot of fuel is sprayed in. Helps to richen it up a bit more when you're up in the RPMs

So if he tosses a 4bbl intake and a carb on it w/ HEI, does he become a SBC? I only ask, because then it wouldn't be any big deal if you beat him
Us 93s do stick together
And if there is ANY 92 Vette owners here, I think you'd be just as welcome ^_^ Yet I've not hard of anyone here owning one, which I find a bit odd!
