I was a line mechanic during the late sixties. I was the guy to see when you wanted a edelbrock and holly installed. Most of the dealership guys wouldn't touch anything 'altered'. I did a lot of cams, carbs, gears, distributors, headers, etc. As a result I worked on/drove pretty much everything, Chevs, Pontiacs, Mopars, Fords and even one Studebaker GoldenHawk. It was my expirience that 1964-5 were banner years for all the brands. Fun cars and the highest quality. In '66-67 everything got bigger and quality started falling. In '71 they cut the compression and cams and quality continued to decline. I still like that 65Pontiac and this 65Ford Sprint.
