Pete Phillips Posted September 28, 2014 Share Posted September 28, 2014 Can anyone help me find a chart of straight eight engine numbers so I can identify what I have? I have looked and looked on internet search sites and come up with everything except what I want. Thanks.Pete Phillips, BCA #7338 Link to comment Share on other sites More sharing options...
nzcarnerd Posted September 28, 2014 Share Posted September 28, 2014 The book The Standard Catalog has the engine number range for each year. If you post the number here someone will reply with the year. Link to comment Share on other sites More sharing options...

sean1997 Posted September 28, 2014 Share Posted September 28, 2014 The BCA judging manual (page 25) also has some info (http://www.buickclub.org/BCA%20JUDGING%20MANUAL/BCAjudgingrev2.pdf) and these links:http://www.teambuick.com/forums/view.php?pg=indent_engine_til_52http://www.teambuick.com/forums/view.php?pg=indent_engine_53-58Series digit is the first digit for 1941 and earlier and last digit for 1942 and later.1930-1955 Buick Master Chassis Parts Book.pdf Link to comment Share on other sites More sharing options...
Pete Phillips Posted September 29, 2014 Author Share Posted September 29, 2014 Thanks to all for the leads. I've now been able to identify all of the engines except one.It is a small series engine, black valve cover (no other coat of paint other than black), lower block is definitely turquoise like other production straight eights after 1941; strange numbers on the numbering surface that don't correspond to anything; has the earlier style water pump; has the bolt holes on the side for the 1948 & newer engine mounts but they appear to have never been used; engine number seems to be 35050W15; or could be 35156W15; or even 85166W15--none of which make sense and there are two styles of numbers, none of which match the normal size and style of Buick engine numbers. I'll try to attach some photos.Pete Phillips, BCA #7338 Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted September 29, 2014 Share Posted September 29, 2014 Appears to me the serial number pad has been ground down and re stamped. Ben Link to comment Share on other sites More sharing options...
Gunner Posted September 30, 2014 Share Posted September 30, 2014 Are you sure that engine is not a replacement engine, sold brand new by Buick to replace a worn out engine. The installing dealer typically hand stamped the worn out engine's number on the pad, as the factory left the pad blank on those engines. Link to comment Share on other sites More sharing options...
Guest buickkuhn Posted October 21, 2014 Share Posted October 21, 2014 This is how my 41 248 straight eight was stamped Link to comment Share on other sites More sharing options...
Mike Albers Posted April 6, 2023 Share Posted April 6, 2023 My numbers have never been there.... any ideas? Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted April 6, 2023 Share Posted April 6, 2023 (edited) Mike I believe they have, and have been ground off. That pad did not originally have "circular" grind marks. Remove the water pump and see if anything is stamped there. Please let us know.

Pete Phillips Posted April 7, 2023 Author Share Posted April 7, 2023 Most states in the U.S. used the engine number, rather than the chassis number, for the V.I.N. on the car's title, prior to 1952 or 1953. If the engine in the car was changed, it's very likely that the old engine number was ground off so as not to confuse one car's VIN with another, if the engine was still good and put in another car. Something like that could be the reason the engine number is ground off in one of the photos above. 1 Link to comment Share on other sites More sharing options...
1939_Buick Posted April 7, 2023 Share Posted April 7, 2023 By the pad with 4 bolts it was originally in a 1948 or later engine. Water pump design/casting changed about 1950 (not 100% sure). Have a photo of pump and the other side? 263ci have a different block casting What is it now fitted to? 1 Link to comment Share on other sites More sharing options...
old-tank Posted April 7, 2023 Share Posted April 7, 2023 (edited) What is the style of the VIN on your title? If it is an engine number then you better stamp that number on the block before you sell the car.

Mike Albers Posted August 16, 2023 Share Posted August 16, 2023 Also, they have assigned it a 16 digit vin on the title. Link to comment Share on other sites More sharing options...

NTX5467 Posted August 17, 2023 Share Posted August 17, 2023 Texas (and probably other states) have a form to complete when an engine change is made in a vehicle whose model year uses sthe Engine number as the VIN. On "modified cars" of those earlier years, when an engine change was made, you could also take the car to the local DPS office and get it inspected for what it is, then the DPS would issue "a number" to use to title the car with. Which might be what the number is on the referenced title. I believe there is a way to "raise" the number which has been damaged on the first block picture? As I understand it, it can be used to see what stamping numbers might have been machined-off during an engine rebuild or otherwise. You might network with some local people to see whom to talk to at your state DMV office to see what their rules might be. Show them the title imaged above and such, too. Just some thoughts, NTX5467 Link to comment Share on other sites More sharing options...
Mike Albers Posted August 17, 2023 Share Posted August 17, 2023 This engine has been in the car since 1950... it was in the car the last time it was registered in 2015, I'm the second owner. 1 Link to comment Share on other sites More sharing options...
