I am Canadian. I have a 261 out of an 1959 Pontiac. After a
e-mail from Evil Dr 235 he has told me that my 261 is different then the US models. I was always wondering about your plug if it was in or out "WHAT". I could not find what you guys meant. Okay anyone out there that has a Canadian 261 that has changed over to a fullflow oil system. Please answer the call tell me if it can be done, if you did it and how. Thanks..
