The Porsche 962
(also known as the 962C
in its Group C form) was a sports-prototype
racing car built by Porsche
as a replacement for the 956
and designed mainly to comply with IMSA
regulations, although it would later compete in the European Group C
formula as the 956 had. The 962 was introduced at the end of 1984, from which it quickly became successful through private owners while having a remarkably long-lived career, with some examples still proving competitive into the mid-1990s.

The newer Andial
built 3.2L fuel injected Flat-6 would be placed in the 962 by the middle of 1985 for IMSA GT, which made the car more competitive against......
