Yes, the 1970 307 I put into my 59 Burb had a canister filter. The early 307, 327, and even a few 350's had the thread in the block to accept the mounting bolt for the canister-type filter, so the engine could have either a canister or a spin-on filter. The difference is in the adapter that bolts to the block with two 1/4" bolts. 307's have a 3 7/8" bore (283) and a 3 1/4" stroke (327). Sort of a Rube Goldberg mixmaster engine!
