ID of rocker arms on L78
 

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

Like this.

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?

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