    Was told this came from a 50's Chevy truck. I think 1953 with a powerglide were the first for the full pressure oil system. Any gurus out there about to tell WTF this came from based on these numbers?

    you are correct about '53 235/PG being the first of the full pressure lube engines. Look at the passenger side of the engine. If the tin side cover goes all the way up to the top of the head, it's a 216.
    If the the tin cover stops at the block/head joint it's a 235......though maybe a dipper system.

    The driver side of the engine at the center bottom is a telltale for dipper or pressure lube....but I forget which is which.

    How does one tell if the engine is a dipper vs pressurized by looking at the engine?

    Only 235's were ever full pressure engines....the reason I explained how to tell a 216 from a 235 in above post. If it's a 216 it is definitely not a full pressure engine. If a 235, it MAY be a full pressure model. That is where the left side comes in.....and the part I can't quite remember the configuration ...

    I'll see if I can find it and repost.........perhaps someone else will chime in before that.

    something about a pressure valve cover on the side of the block if it's a dipper? but I forget.

    Does that say LAA on the engine stamping?

    if so, that makes it a 1953 235 manual trans engine, which should be a dipper

    Okay...I think I got it......on the left side, bottom of the block along the pan line....If there is a kidney shaped tin cover with three screws and a small looping tube...it IS NOT a full pressure engine..it's a dipper system. Absent the above, it's a full pressure model.

    It does say LAA on the stamping. I'll take a closer look to verify the above information. Thanks fellas.

    it's been 40 years since I overhauled one of that particular type :)

    Search for : Inliners International website. On the left side of their home page is a tab for a list of block and head numbers. Use the last six digits for the pics you posted. Look for casting # on head also, near #2 cylinder on driver's side. K6

    I am pretty sure that pressure oil 235 engines in 53 only came in cars with the powerglide. Trucks didn't get an automatic until 54 and then it was a hydromatic 3 speed. I learned to drive in one.

    I vaguely remember that you can convert a copper to pressure fairly easily. Correct?

    I'm thinking that would require drilling the crankshaft throws from the rod journals to the mains journals......not what I would call easy, unless a 235 pressure lube crank fits a 216 dipper engine. Either way, there would be additional mods to make and it seems easier to just obtain a pressure lube engine as they are fairly easy to find.

    I was thinking 235 dipper to 235 pressure, but probably cost as much as rebuilding a pressure motor so probably not a lot to gain.

    Sell it and get any GMC, all pressure engines and better all overall even the lowly 228"

    As has been stated the left side of the engine will have a tin “kidney” that’s a dipper engine
    A dipper can be converted to pressure piling but it’s pricey
    Pull the oil pan to know for sure , engines can always be swapped and the 235 is as common as toast bread with breakfast.
    Great engines, a little pricey to built but reliable and cheap to keep running !

    As I understand your post, it says the 216 and non-pressure 235 both have the tall tin side cover (goes to the top of the head). In my experience, that is incorrect. I believe ALL 235 engines regardless of oiling system, from at least 1950 models, if not before, have the short tin side cover (stops at top edge of block).

  22. I avoid the not pressure six like the plague, I thought it was all the non pressure engines had the tall side covers. I know there was a 53/53 Chevrolet firetruck (dual rear wheels) in town it had a 235 with a tall side cover.

    @'Mo could answer this question

    Side note the Sun tach sending unit off the fire truck is now on my 53 Chevrolet 150.

    As stated, the driver side 3-bolt 'Kidney -bean' is a sure indicator of of a dipper motor.
    All Chevy 235's 1950 and later had the short side cover.
    The pressurized 235 was introduced in 1953 (P.G only).

    BTW, The dipper motors have cast iron pistons, and can be made much more reliable when converted to aluminum pistons. Later 235 pistons are inexpensive, and a direct replacement. (They will also work in a 216 with .060" overbore.)
    Re-balancing the motor will not be necessary.

    Anyone know if the 1953 PG 235 had 2 center valve cover bolts, or the standard 4 hole perimeter arrangement?

    All '53 235's had the two bolt valve cover. 4 bolt perimeter covers started in '54
