[QUOTE=PRNDL;1573654736]There were 611 corvettes made after yours. Nobody knows how many were bigblocks. The available records do not associate vins with options.[/QUOTE
Well, there were 15,441 built with the 427, which is around 40% of all the cars produced in '69. Multiply 611 remaining by 40% and you have around 240. They call this "interpolation."

Unless of course there was a shortage of 427 heads, and they stopped producing big blocks until the 1970 run.
They call this "assuming".
That being said, you're probably right, the number is in that ballpark.
