Hey guys! It's been a while. trucks been sitting for the past 6 months or so unfortunately, but it is what it is. started it up and drove down the street only to run out of gas, haha. had to push it back about a block.

Anyways, reason of the post. It has been said that the only way to tell the difference between a 240 and a 300 is by actually measuring the stroke. I brought it up once and it was never really resolved as a fairly concise way of differentiating, that the the oil pan on the 240 has the drain plug more to the drivers side, whereas the 300 has it almost dead center. I discovered this by looking at the 300 and 240 I have built 8 days apart, one may 12 1965, the other may 20.

I'm hoping you guys on here with either or both engines can help us all decide as to whether, in stock form, this is an official way to differentiate the two if they have stock oil pans. also remember I found it on 65 engines, it might not hold true for 66s.

Thanks everyone!

 

Joel, Forgive me for asking, but in the second paragraph, second sentence,........ is there something there that you don't understand???

As far as I know the engine in my 66 is a 240, and the oil drain plug is dead center on the back of the pan. I don't know what this does for your findings. It could be a case like the 65/66 grills. At some point Ford decided it was stupid to make 2 pans, or that this pan or that pan had a flaw and went to the other pan exclusively. Who knows?

 

240 was installed in cars. Hence a possible differing pan. the 300 was never installed in cars.

There are a multitude of pans for the 240 300 based on the applications in cars truck or vans and even four wheel drives.

Joel, how did you magically figgure the engines are eight days apart?
