So after surfing here a little bit and seeing a few things to look for on my engine, it looks like I have a 235 and not a 216 in it. I started looking at the side plate and finally scraped off the serial number, HEA is the prefix. It looks like a 1950 motor, with a 1952 cab. Any other numbers on the frame anywhere so I can see what that may be? Is this still a splash oiled 235 or were 1950 235's pressure oiled? Still learning about these, so forgive me if it's been asked before.

Thanks!
