Howdy,

I can't believe someone wants to pay >$20k for this thing.

I _really_ can't believe that doesn't meet the reserve.

I thought all IROC's had the TPI engine? 85's was the only year that had the 1226870 ECM, which is usually replaced by the 1227165 or 1227730 when it comes time to do tuning.
