DIFFERENCE BETWEEN CHEVY ENGINE 216 and CHEVY ENGINE 234

[serge]

Hello

I would like to know what are the external difference between these two engine.
The engine of a HUP I am mounting, seems to have some external difference with the engine describe in the good web site of PHIL WATERMANN.

Among these difference , I have to note that I have no supplementary oil filter at the top of the engine, and that the command of carburator is between the intake and exhaust manifold (red swallow) .

Best regards Serge

Hi Serge

I think your arrow is pointing to a vacuum port. Can you post a closeup photo of the fitting in questions.

Here is a photo of the original oil line connections on my `45 HUP with 216 engine and the top oil filter.



The Chevy intake manifolds have many different vacuum port locations I can't prove it but I think each of my trucks had slightly different manifold taps.

If you need a larger photo here is the link http://canadianmilitarypattern.com/R...mera%20046.jpg

Hello PHIL

I thank you for your answer and I have been surprised that the engine of your HUP was a 216 engine because it has more items than my engine and so I believed that it had an upper number (234). So using the pic I have previously posted, is my engine an engine used during the war on the CMP and what is it's number?

I join two pics : one from your web with an larger view and the other an more accurately pic of my engine.

Best regards Serge
