I know this is an old thread, but that was a good read. However, I do take exception to the statement that "no production SS camaros were made with an engine smaller than 350. Back in the early '70s, I knew and frequently rode in two SS250 6-cylinder camaros. One with a two speed powerglide and one with a three speed stick. My best friend at the time(1974-75) had a tahoe turquois 1967 SS250 camaro with a powerglide. It had the white bumblebee stripe around the nose and a black interior with console floor shift. Not long afterwords another friend got a '68 SS250 stick shift, white with a black vinyl top and black interior. No console but had the stripe that wrapped around the nose then on down the sides of the car. They weren't fast but they were cool!
So while I won't dispute the 327cu. info, I know for sure that smaller engined SS were available in '67 and '68. Just my two cents.
