most likely a 12 bolt 373 ratio, but it can vary depending on the model.
yes, but the speedo will need to be reset and the fuel milage will drop
My RPO says my 1996 Z28 has a 273 Posi ? Is that for real ? It doesn't feel like 273....feels much more like 373 or 342 !
Yes. A 373 you will lose a couple miles per gallon and run 3,000 RPM at 60 MPH.
1 and 373 are the only factors of 373, since it is prime.
Get your rear-end waxed.
get a posi traction rear end and swap it out.
