could this be part of the ultra rare corvette option

In 82 - 84, GM put the 2.5 iron duke inline 4 in the camaro and firebird. It was somewhat common, but not many are still around these days. So, that could be called rare.
But I don't think I know ANYONE... who would want one... let alone, pay top dollar for it.
Besides... lats face it... that thing, while being real neat... is ugly.

The 4 cylinder was actually the base engine until 1986. The horsepower was downgraded in 1985 from 92 HP in previous years to 88 HP for the '85 and '86 years. You're right though, rare does not mean desirable. The best thing about those cars were the 4.10 geared rearends. We used to buy the rearends on the cheap to use in street/strip thirdgens back in the day. A 4.10 geared 4 cyl camaro/firebird reared would really wake up a 2.73 or 3.08 geared IROC or T/A!
