I believe this was the part # 3896929, now part # 12364051.

If you need a cam (and I imagine other parts as well), it might be a good time "improve" on the performance while you have everything apart.
What are your plans?

Carlo,


Now that Mike has kindly provided the GM #, you can go a couple of directions with that. You can search this board with it, which will probably turn up lots of threads with good info in case you might want to use a "better" cam. Or if you're sure that's the part you want to use, you can go to NAPA's web site, click the INTERCHANGE box, and do a search with the GM number. I came up with Sealed Power Part Number: SEP CS274
I suspect that Sealed Power also has a cam and lifters kit, but I don't know the part number for that.

12364051 was a Crane-manufactured camshaft kit with lifters sold under a GM part number. It was discontinued a long while ago.

That 274 NAPA or the sealed power or crane equal is the most wateredown broomstick they have it was listed for every stock small block to meet all emissions in all states.If you are rebuilding complete use the early stock flat top piston a consider a cam built you with 2013 technology done on CNC equipment.

Re: 1979 L48 Camshaft

If you are going to pull and rebuild the entire engine why not up the performance a bit? You could bump up the compression a bit, upgrade to the bigger valve heads, have the heads ported, use the L-82 camshaft, etc.. The engine will still look stock and make quite a bit more power.
