    :confused:i have a 46 chevy 1 ton plus wrecker. It has a 235 chevy motor in it. My friend says he has another 235 he will sell me. I have in the back of my mind it is a 216. It is in a 47 chevy 3/4 on long bed. The 235 i have has a different place where the top radiator hose hooks up. The one my friend is attachec directly below the radiator center. Can someone help me out on how to tell the diference between the 216 and the 235? Also will a starter off of a 216 fit on a 235? His truck is for sale.

    216 side cover tin goes right up to the valve cover, 235 it ends at the top of the block.
    235 splash oiler has a triangular tin plate just above the pan rail behind the exhaust pipe, the pressure lubed engines don't have it.

    '50 up 235 has the short side plate, '41-'49 big truck 235 looks same as 216 outside.

    wrong, 54 to 62 235s have the short push rod side cover because the early 50s 235s are bored out 216s and have the tall cover

    I have to say wrong to both of you. As a big truck nut, I have had several unrestored untouched 1946- 1953 2 ton trucks. The 2 tons always used a low oil pressure 235 until 1954. The 1-1/2 tons used a 216. The 1940's big truck 235's still had short push rod covers just like the better 1954-up car truck engines, but they had the valve cover held on with 2 nuts on top instead of 4 on the sides like 1954 and up 235s. They still had the triangular oil pressure piece near the exhaust pipe just like a 216. The early low pressure/splashed oiled 235 is potted by==short push rod cover, two nuts on top of valve cover, and triangular pressed steel plate on driver's side just like a 216. Also the head is a little oddly shaped on the passenger when compared to later 235s. The starters should interchange. But the 1955 up 12 volt starter has a different number of teeth on the starter and ring gear!

    This is a photo of a 216 or low oil pressure early 235. Note the small stamped piece of steel held on by three "stove bolts" bolts/flat head screws, just below the exhaust flange. That is only on the splash oiled engines.

    The short stamped steel push rod cover as seen on this 1955 up full pressure 235 engine is also on the very early 235 big truck engines. If your push rod cover goes clear up over the spark plugs, then you have a 216 engine. Also the full oil pressure 235 and 261 engines will NOT have the small stamped piece of metal just below the exhaust manifold.

    This engine is a 216. The tall pressed steel cover that extends over the top of the spark plugs is the dead give away. Also any 216 or 235 engine with this type of valve cover is going to be splash oiled--- with the exception of the 1953 car 235 engine.

    All is getting confusing!:confused:
    1940's Chev. 216's and 235's are weird engines to spot the subtle differences.

    Best bet is to get the engine casting numbers , and the engine serial numbers from the motors. Then look up what you have.

    The early 235 (4-way Lubricated, Heavy Duty ) were an early option on 1-1/2 Ton Chevies & COE's.
    They are not bored out 216's.
    They began in late (Oct) 1940 and have different cylinders blocks, pistons, rings, connecting rods, crankshafts, camshaft, tappets , push rods, oil pans--- then that years' std 216 motor.
    Those early 235.5's {late 40'-49'} have the tall {9-1/2" X 26-7/8"} "Valve Push Rod Cover " side covers that extends to cover the spark plugs. Later 1950' -52'-53' had shorter Valve Push rod covers {5-5/8"X27"} and the 53' had an extra dimple in the center.

    Later "full pressure lubricated" 235's ran the same 5-5/8" X 27" side cover.

    All this is finely splitting hairs, and for most folks the engine casting numbers, and the engine serial number are the easiest ID.

    Wrong The 235 with the tall side cover was a truck engine. In 1950 the power glides had a 235 with the short side cover.

    Wow, my head is spinning. I have a 48 1-ton (that's new to me) and thought it had a 235 in it. Now I need to check... and see if I can even make any sense of it.

    To split hairs even finer, no stovebolt cast-iron-wonder (216 or 235) was truly "splash oiled" past 1935. They are technically a 4-Way Lubricated engine, or a Chevrolet Specialized Combination lube system, or best described by the SAE term : "Modified Splash System" of lubrication.
    This has nothing to do with the OP's post, it's just OT trivia to add to the weirdness of those motors:D

    Gotta check the casting or serial numbers on the block to give a true ID.

    I will check the casting numbers tonight. I a pix i snapped earlier on my cell phone it looks like i see a 848 with a G2 to its top left then a 850 below. Is this the engine serial number? Where would the other numbers be located ? Thanks to all HAMB folks for the help!! I will post some pix soon of my pride and joy. Wreckerman

    If you have the correct exhaust manifold that came with the engine, the exhaust outlet on a 216 points straight down. On the 235 it points down at an angle. Also I don't ever recall a 235 with a side pan going all the way up to the head. I have a 1946 216, a 1950 235, and 2 1954 235s. The 1950 235 is the low pressure, Babbitt bearing, straight 6 and the side pan only goes up to the bottom of the head just like the 1954 235s.

    As stated before, '41-49 235's were externally the same as the 216 including the tall side cover.
