235 vs 261 oil lines
Bob- If the engine you are looking at has small oil line fittings I think that it is either a 235 or if a 261 it is not the late 261. Take a look and see if one of the oil lines dumps straight back inside the block. (See picture of 235) On the engine that I know is a 261 both of the oil lines are huge nominally 24/32ns diameter you will see that one goes to the oil passage that travels down the side of the block while the other comes directly from the oil pump fitting inside the block. (See Picture 261)
