I see some of the usual historical mis-information made it into the chat yesterday:
"[Comment From KentWatkins KentWatkins: ]
No comment on the Z28 then? The Z28 was brought out to battle the Boss Mustang back in the Trans Am days."
When the Z/28 was brought out there was no Boss 302, Ford was still racing the 289cid engine. Then Ford came out with their Tunnel Port 302 Trans Am engine for the '68 Trans Am season and it was a failure. It was then that the Boss 302 was brought out.
