Out of the Museum collection, we have this 1969 Yenko Chevelle. This would be a one year only model, limited to only ninety-nine examples. All of these cars would be powered by the 427 CI L72 V8 engine, rated at 425 horsepower. There are only two Butternut Yellow cars built, this one being the automatic transmission car, and the other a four speed manual.
