What everybody else said, plus here's a bit more. Yes, definitely a full pressure 235, not a splash oiler. The block casting number 3835911 in my reference material indicates used in 1953-55 Powerglide equipped passenger cars with a hydraulic cam. The head casting number 3835913 indicates 1954-55 with 4 bolt valve cover mounting and small temp sender port. Your pictured serial number 0745244F54Y decodes as:
0745244 = the 744,244th engine from the production line
F = Flint Engine Plant
54 = 1954 model year
Y = Passenger car 235 equipped with Powerglide transmission(all such engines came with hydraulic cam and lifters)
On the 2 "Acorn" nut valve cover, many 4 bolt heads were converted to that style with a few simple parts for looks or to make it look like an earlier engine. If you look closely at a zoomed in version of your pic below, you can see the valve bolt hole casting bumps along the edge of the valve cover. You can also see the head casting number 3835913.
As I am currently running the same 1954 235 out of a passenger car in my
Grandpa's truck, I can attest to the info on this particular engine. Great thing about this engine is the water pump is still in the high-mount location best for our AD series trucks, so no modifications needed to relocate that for better cooling that is needed using the later 235s!
