Re: G92 option
G92 (performance axle ratio) available only on IROC-Z with 5.0 TPI (LB9). G92 was available on IROC-Z convertible in 1987.
All 1987 350 TPI (B2L) IROC-Z's came standard with the 3.27 BW rear end

Re: G92 option
There is also a 1LE option,which is similar to the G92. My brother had it on his 91' 305 formula. Bigger brakes, 3:42 gears, big rotors, radio delete, N10 option dual ypipe etc,etc.

Re: G92 option
thanks, I was just wondering. I have 87 5.7 L98 motor. I thought I had all the options available for that year on my car.
I was looking at the old Camaro Dealer order sheet and I thought there was a option that you can get the G92 package but its only available for a 305. That makes sense.

Re: G92 option
350 in '87 only had one axle ratio so G92 wasn't available
G92 isn't really a option as such , just a factory indicator that a optional " performance " axle has been installed
if one was available. The actual installed ratio has it's own RPO code,typically GXX
Some GM axle codes
GH0 : AXLE REAR, 3.54 RATIO
GH2 : AXLE REAR, 2.29 RATIO
GH3 : AXLE REAR, 2.77 RATIO
GH4 : AXLE REAR, 2.92 RATIO
GM1 : AXLE REAR, 2.59 RATIO
GM3 : AXLE REAR, 3.45 RATIO
GM8 : AXLE REAR, 2.56 RATIO
GN9 : AXLE REAR, 4.11 RATIO
GT7 : AXLE REAR, 3.33 RATIO
GU1 : AXLE REAR, 2.41 RATIO
GU2 : AXLE REAR, 2.73 RATIO
GU4 : AXLE REAR, 3.08 RATIO
GU5 : AXLE REAR, 3.23 RATIO
GU6 : AXLE REAR, 3.42 RATIO
