Lot #60 - This is an excellent example of the final year for the model, with 15,600 original miles. It's equipped with the final-year legendary L98 engine, a 350ci 5.7-liter engine. A 4-speed automatic transmission was the only transmission available for the L98 optional engine and, for this IROC, was configured with the optional G80 limited-slip differential, G92 performance ratio rear axle, oil cooler, 4-wheel disc brakes and 16" wheels. This accident-free IROC-Z shines in its factory-correct bright white paint with gray and yellow IROC Z/28 graphics. The black interior is optioned with factory-ordered, custom black-and-white houndstooth cloth bucket seats. With performance in mind, this IROC Z/28 only includes the interior options of air conditioning, full analog gauges and a Delco AM/FM/CD player radio. This IROC Z/28 has lived in California and Texas before becoming part of an Arizona-based collection of rare General Motors vehicles. Other than a Flowmaster exhaust, this vehicle is in excellent stock configuration, only receiving replacement OEM parts as part of the normal maintenance requirements. Recent work includes replacement of all fluids, rear tie rods, rear shocks and hood supports. The IROC Z/28 will be conveyed with recent maintenance history, original Window Sticker, owner's manual, dealer brochure, period advertising, and the car show display board. CARFAX shows manufacturer safety recall issued on 06/01/1990: Seatbelt buckles.
