I agree on parts being mis matched or using what was available, a couple good friends worked at the Corvette factory in St. Louis many years have told stories about things that happened every day.
I recently tore down an early built 1969,302 engine, everything was correct except it has the 3279 large journal crank,so i was curious if this crank carried over to some early built 69 engines, anything is possible from back then.
