i am speaking mainly about the 54 235 engine
i do have a 261 however i don't know what year it is since there is nothing stamped on the pad by the dist i would do that too.
the ext oil canister was given to me plus i have another one that is currently on the 216 that i will replace with the 235 (going into a 51 3100)
i am leaning toward the bypass filter. is there a diagram of how that would be set up?
thanks
