I did the math
the SHP 427 engine production to car production percentage is way over normal on 3 of the 4 special HI PO builds
The Fran Preve article "The Numbers Game" said that engine production was 2 to 5 percent over car production . He was talking about regular production engines and cars and he must not have known the COPO 427 car production numbers at the time of the article (1987)
Here are the numbers I have on the 427 COPO engine production to car production percentage and included the ZL1 Corvette since it was also a special HI PO build
ZL1 Camaro 88 engines to 69 cars = 22%
L72 Chevelle 358 engines to 323 cars (using RPOs) = 10%
L72 Camaro 1015 engines to 997 cars (using RPOs) = 2%
ZL1 Corvette 94 engines to about 3 cars = about 96%
