1987 IROC 5.7 Trans Question
Is there anything I should know about the 1987 IROC with 350 cars as everyone I have test driven shifts hard/firm. Did they do something different than what the 700R4 add in Formulas and GTA Trans Ams? Just curious if GM gave them a more better or beefed up trans.

Did GM ever put Corvette transmissions in the IROC Z 350 cars?
