GM's Secret 302 Z28

摘要

Any gearhead worth his gear oil knows the story behind the famed Camaro Z/28. But just in case you've been holed up in a cave the last 30-something years, here's an abbreviated history: Beginning in 1967, Chevrolet built a limited number of high-strung road warriors, aimed primarily at SCCA road racing, that incorporated a high-re wing 302-cu-in. V-8 (305 cu in./5.0L was the SCCA class limit), a bulletproof Muncie four-speed manual gearbox, and heavy-duty suspension and brakes. Getting one was as easy as checking the RPO Z28 option code on the order sheet. SCCA rule changes for 1970 allowed the Z-28 to pack larger 350-cube V-8s.
