Just checked the Ultimate Guide to American V8s 1948-1976, the only listings for a 2 bbl 327 is the 235hp (full size passenger) and 210hp (Camaro) 327s sued in '69. The only other variation from the 4bbl equipped 327s are the 360 hp and 375 hp engines from '62-'65, which were Corvette Feul Injection engines.
