ID of rocker arms on L78

[boomer632]

Was adjusting lash and was curious to see if anyone can ID the manufacture of these rockers. On a 69 L78 Camaro motor. I did google search and found some with same "C" made by Elgin but the C was facing away from the rocker stud.

All the original L78 motors I have seen are stamped with a L for long slot. There may have been other manufacturers

These have the same markings as yours. I have the same set on my L78.

Thanks Dave! Mystery solved!!

Good info. Will check my 69 Chevelle for curiosity sake.

I wonder if my motor has a Crane cam too? Do or did they make a solid L78 spec cam? I definitely have a solid cam as I can see the C clips in the lifter tops when I look down through the heads where casting voids are.

Why do the C-clips show they are solid lifters?

Is this not correct?

[SuperNovaSS]

No. If there was no clip at all it would be solid. With any kind of clip it could be either solid or hydraulic.
