I have a cam that came out of an over the counter LS6. '71 or '72 vintage as best I can recall. It was replaced with an aftermarket cam before it was installed and this cam was never run. It still has the factory paint marks on it. The only casting number I see on it is 4366. Could this be what you are looking for? It doesn't have the whole 3904366 number on it.

I think it is the one I'm looking for, My parts book also shows this # for 1971 Is there a casting symbol on the cam OMO

There is a OMO next to the fuel pump eccentric. The O's are solid. More like dimples than O's, but I can see why they are referred to as O's.

I just traded 2 NOS 3863143 camshafts for the correct original LS-6 camshaft, 3904362. Was still in the original container, it is stamped 3904362 and nothing else on the end, with the original paint marks. Camshaft was purchased by parts manager person in 1976.

What is the difference between the 143 L-78 Cam and the 362 LS-6 Cam? I thought they had basically the same lift and duration?

According to Chevrolet records:
Cam #143 has:
*Lift-.497/Intake & .503/Exhaust
*Duration-348/Intake & 348/Exhaust...dated 1965

Cam #362 has:
*Lift-.520/Intake & .520/Exhaust
*Duration-316/Intake & 302/Exhaust...dated 1970

Both of these Cams are Mechanical lifter w/1.70 rocker ratio.

In addition to what mr70 stated, 3863143 is correct for 1965 396/425hp and 1966 427/425hp. 3904362 is correct for 1967 427/435hp, 1968 427/435hp, 1969 427/435hp, & 1971 454/425hp, of course these are Corvette applications I'm listing here.
