Nope, they really did offer 302 DZ conversions in those cars. Think of how they would do in the cubic inch to weight classes of the day. The closest I personally have found are a '69 Z28 [owned by Ron Normann], and, my 70 1/2 Z28, both sold at Nickey, and, with paperwork showing the performance modifications performed by Nickey. Actually, the car that Don Swiatek, who ran the hi po shop, chose for his own race car, was a Z28. Because of that, Nickey put a lot of work into getting the 302 to perform. Kind of odd when all we usually think of is built up 427 cars.
