Once again I want to say that the "W" motors '58 thru '65 348, 409 and Z-11 427 also all had 1.75 ratio rockers. Has anyone looked for these?

I know the 425hp/409s used some 315# springs , so they are pretty strong, I'm almost sure I have seen some in articles with the aluminum Harland Sharps.

Surely not all these have vanished from the face of the earth. They were of the standard Chevy design of stamped steel/ rocker balls, and threaded studs (hi-pos were pinned to the cast iron sockets to prevent stud pull-out)
