Car: 86 sports coupe-83 berlinetta

Was the gear ratios set in stone?
I know from what Ive seen that 5.7 cars got 323-327 fpr performance gear, 273-277 for standard gearing.
Ive seen where L69 cars got 373 with the 5 speed and 342 with an automatic. I have a friend that has an 84 l69 car auto with 373s.
I guess what Im saying was it possible to if you were in good with a chevy dealer you could order a 5.7 car with 342?
I know it is all about the gas milage.
Im not talking a copo car or anything, I know the 5.7 could never be ordered with a t/5 because of reliability issues. But a stiffer gearing would ad or subtract from reliability.
Thanks Randy

NO, you could not order a option that was not specific to the car model. You were lucky to have a option of two gear ratios on a 350 car and most dealer ordered cars had the standard 2:77 ratio.

My friends car is an 84 L69 car. It has the 700r4 and has a 373 open diff. It has the parts tag in the glove box GT4 option.
is it uncommon to have 373 with an auto?

I see, either way 373s are a good gear. Im pretty happy with my 345.
