This is the pushrod listed in the crankcase figures as serving both inlet and exhaust valves, part number 41-0790. It's the rod that rides in the tunnel between the tappet and the rocker, transferring the lift off the camshaft up to the rocker arm so the valve opens on schedule.

Our catalog record ties it to the crankcase area and shows it appearing across catalog listings from 1969 to 1970. Beyond that, we don't have more detail on this one in our own records — no dimensions, no material spec on file here.
If you're matching this against what's already in your engine, bring the old pushrod to the counter or measure it before ordering. Call the shop and we'll help confirm fitment before you buy.
