May help indentify I`ll get a measurment and post it. I think `36 Buicks only had a 233 and 320, and I think neither, has the water jacket side cover.

MCHinson Posted September 9, 2019 Share Posted September 9, 2019 If the number you have posted is the full number, I think it might be earlier. Buick Straight 8 engines started in 1931. I don't have any experience at all with 1931-1935 Buicks. In 1936 (and later) there would have been a series identifying number before the basic number. I suspect that engine to be between 1931 and 1935, but I have no idea which year. I did find one old post on the forum through a Google search that shows 1931 engine numbers running from 2460544 to 2602732, and another post identifying engine number 2,830,538 as being a 1933 Buick, so I would make a guess that your engine is probably from either 1933 or 1934.

Marty Roth Posted September 9, 2019 Share Posted September 9, 2019 Here are pictures of my former 1934 50-Series engine. The water return tube on your engine is above the block. very different (likely earlier han mine). Hope this helps, even if just to show the differences Link to comment Share on other sites More sharing options...

I also notice the fuel pump and starter are on opposite sides from the engine I`m trying to ID. The engine I`m trying to ID is not mine, it belongs to a friend approx. 300mi from me, reason I`m waiting for a head length to post. I did find a picture of an engine removed from a `35 90 series that looks similar. Link to comment Share on other sites More sharing options...
nzcarnerd Posted September 9, 2019 Share Posted September 9, 2019 I recall from the info charts that I received from Buick in the 1970s that the 344 engine from the Series 90 was 1100 lbs fan to clutch. Maybe you have to lift the head and measure bore and stroke to determine which unit it is. The Series 60 engine is similar looking but physically smaller I believe. Unless you can find a going Series 60 car - they are more common than the 90 - and measure the length of the block. Link to comment Share on other sites More sharing options...
JayG Posted September 9, 2019 Share Posted September 9, 2019 It looks like a 60 series. The 50's didn't have a water return on the top of the head. The 60's had a 4 tube return as shown in your picture. The 80's and 90's had a 6 tube return. Link to comment Share on other sites More sharing options...

JayG, I`m pretty sure you nailed it, with the water tube 4 and 6 inlets and being a 60series, along with the engine number it falls in the `35 year which would make it a 278.1cu.in. 100hp..

vernludwick@att.net Posted April 20, 2021 Share Posted April 20, 2021 I have a 1933 Buick 60 series with the same engine......272ci The other two engines are different and the same ......the smaller one has the starter on the drivers side and the larger 344ci has the starter on the passenger side like the 272.....the 344 has a different radiator pipe with six legs....the 272 only has four and the feet are in a strait line......only the 272 looks like yours.

Can you measure the bore or stroke? Some one may also know the length of the heads for the various engine sizes From posts above can be a difference in the water return tube. Edit Look here. Not the best quality. A lot of info on this web site, but hard to find. Search does not always work well. https://buick.oldcarmanualproject.com/manuals/1932/page1.html Edited May 12 by 1939_Buick (see edit history) Link to comment Share on other sites More sharing options...
