AC Spark Plug-Flint Lifer Posted March 5, 2019 Share Posted March 5, 2019 I have a friend who needs to accurately identify a Buick V-8 head that was rebuilt in the past but never installed. I want to help him but could find no info on these number Out There on the web. I'm a long-time BCA member but brand new to this forum. The head has the following numbers cast into the head: "B24"..."B1237650" (is that a part number?) and a big "7". That's all I could find in the casting. There's no machined surface that might have a number on it. Thank you all. If needed, I can take a digital or two and post that. Link to comment Share on other sites More sharing options...

AC Spark Plug-Flint Lifer Posted March 5, 2019 Author Share Posted March 5, 2019 (edited) Thank you for your response Smartin. However, how did you know? Was that a part number? Just asking for data/where to look for verification. I know the engine parts are in group 0.000 in the parts books, but all of mine are older or much older than that. Is there a website(S) out there that carry Buick searchable parts I.D.? This is the first time I've been on a forum except the rare times a friend sends me a link. Again, thank you. It gives me incentive to buy a later parts book. Edited March 5, 2019 by Dan In Flint I needed to complete a word. (see edit history) Link to comment Share on other sites More sharing options...
Smartin Posted March 5, 2019 Share Posted March 5, 2019 Yes it is a casting number. Just google Buick head 1237650 and it will take you to it virtually. Link to comment Share on other sites More sharing options...
RivNut Posted July 9, 2019 Share Posted July 9, 2019 (edited) Oh Yee of little faith. Don't look a gift horse in the mouth. I would imagine that it took you longer to type out and wait on a response than to try what Adam suggested. https://www.teambuick.com/reference/casting_numbers_350.php Buick 350 (5.7) Casting Numbers Head Cast # Year Displacement 1232650 71? 350 1233472* 67-72 350 1237650* 70-72 350 1238145* 67-72 350 1233472 67-68 350 1237650* 70-72 350 1237749 70-76 350 1238145x 68-74 350 1240143 70-71 350 1241861** 72-80 350 1242145* 72 350 1242556* 70-80 350 1243452** 72-80 350 1247716 70-77 350 1382546 68-69 350 1382546* 68-74 350 1382720 68-70 350 22505236 73-80 350 22505238** 72-80 350 243452** 75-79 350 * Oils through push rods ** With A.I.R. 350 heads are 58cc Edited July 9, 2019 by RivNut (see edit history) 1 Link to comment Share on other sites More sharing options...
