87 iroc gear ratio???
ok, i found an 87 iroc with disc brakes in the back, its all original and i was wondering what the gear ratio is, it has a tpi 305 and an automatic.
the vin is 1G1FP21F2HL151560
The vin is how i found out it had a 305 and that it was an 87.
also do these cars have aluminum radiators or aluminum drive shafts like a gta? and are any of the parts on the car better than my 86 base firebirds?

Re: 87 iroc gear ratio???
All the 87 305 TPI IROC-Z cars with automatic transmissions have 2.73 gears unless it has the G92 option. Then it would have 3.23 gears
Aluminum rad? Doubt it but maybe
Aluminum driveshaft, no.
There's nothing special about the 305 IROC-Z.
