The air cleaner that mr409 has at the link supplied is correct. I can also add that that air cleaner was also used on the '65 - '67 396/325 (chrome lid when used on '66 & 7 Chevelle SS & ElCamino); '66 & 7 427/385 (chrome lid on Impala SS427); and '67 Camaro SS350 (chrome lid). The 283 used a similar looking style but it was smaller diameter (may also have come on '67 Camaro 327 2 barrels, I'm not 100% sure).
MR409, is that 327 picture of a '67 Chevy II 327/275?
