Camshaft ID help gm part # 3752677

Could someone please help me identify a camshaft, GM part # 3752677. Any help would be much appreciated. Looked on the forum and internet and not much there??!! Thanks in advance for helping out.

The number molded into the camshaft casting is the finished camshaft part number/drawing number, but you won't find it in any parts catalog. That's because replacement cams are an "assembly" consisting of finished camshaft and indexing pin. The finished camshaft and cam/pin assembly part numbers are sometimes sequential - not always, but rarely vary by more than about 50 since the paperwork for both went through the system together. For example the '57-up Duntov cam finished camshaft assembly is ...098 and the cam/pin assembly sold OTC is ...097. In my parts references I don't find anything close enough to be a candidate, and I don't even know if it's a Chevrolet part or other GM division, but Joe L. can probably nail it down.

Duke, thanks for the information. FYI: the actual part number, not casting, is on the GM shipping tube label, 3752677, so it is a GM part. Hope Joe Lucia can chime in! Thanks again.

Duke the tube is not open, so I do not know. Thanks

This is a tough one. At the moment, I cannot positively identify it. I can tell you this about it, though:

----it was almost certainly released sometime in the 1958-59 period;

----I can find NO Chevrolet passenger car or light truck application for it;

----it is a Chevrolet part number but that does not guarantee that it was ever used on a Chevrolet application;

----it was discontinued from SERVICE sometime in the 1976-81 time period.

At this point my guess would be that this was a camshaft for a non-Chevrolet application, a HD truck application, or an industrial engine application.

Joe, thanks for checking on this for me. I could not find anything either. So, I guess it will be as you describe it for now! Thank you.
