My cousin has a '67-800 Scout, his motor is painted that same yellow, under neath the po's red paint. Also on looking for motor size, you can tell by head #'s under valve cover and on under side of the head. Jeff
I indeed found the number stamped on the engine…but now am more perplexed…"3919". What does that mean. At first I thought it just said 391…but then I saw a fourth number peeking out. 3919.
What does that mean?
I think it means you're looking at the wrong number. If there aren't any other numbers, then the engine is probably a 266. Not all 266 engines were stamped on the engine id pad from what I've heard.
