Before you point me to the page that everyone has read:http://www.camaros.org/geninfo.shtml#COPO
Why do the ZL1 production numbers (90) and crate engines (17) have a tilde (~) in front of each (~90) and (~17)? That seems odd. Does this mean that these numbers have been questioned in the past and that at least one historian "in the know" remembers a different number? It not only seems odd that Chevrolet didn't produce more that ended up in R&D and other racing programs. Wait! What am I saying? Chevrolet wasn't racing.
In Paul Van Valkenburgh's book,"Chevrolet ---Racing?" he refers to aluminum big block 427's in racing. He states, "Penske immediately picked up a half-dozen which were shipped to Traco, McLaren bought a bunch, and the 1968 Can-Am season was off to become a relatively competitive series." He also states, "The production aluminum-block 427 Chevrolet engine saw finally made available to the general public. Most were sold across the counter at around $2000 for the short block, but some were built in Corvettes and Camaros."
Is the ZL1 that we say only (~90) were produced, is that only complete engines? I take that as meaning there were A LOT more of these blocks produced, but only (~90) were complete engines. Any insight?
