Can I tell 1.5 vs 1.6 roller rockers from measuring?
I have some aftermarket aluminium boxy shaped RR's of unknown ratio.
Across the top they measure 2.75 inches total. From the pushrod end to the center of the stud hole they measure 1.25 inches. From center hole to rocker end they measure 1.5 inches.
Anyone know the ratio.

My Crane's are stamped right on the top and I thought all manufacturers stamped them on there somewhere. Maybe I'm wrong though

Measure center hole to the push rod end. If that's 1.5 as well then I would say they are 1.5 roller rockers. I know with 1.6 you have to elongate the push rod slot so I would assume the cause of this is a 1.6 inch measurement from center hole to push rod end.
