Reply to "Identify rocker arm"

George PAdmin.

A rocker such as the one pictured, stamped with 1.7, indicates to me a BBC rocker arm, or it could be a high ratio 302/351W rocker arm. True, in a few instances people have used the BBC rocker arm as a substitute for Cleveland rocker arms, but the BBC rocker arms are not dimensionally identical to Cleveland rocker arms, the substitution is not ideal, it is not something I would do myself.

Yes stock 351C ratio is theoretically 1.73:1, as was the rocker ratio of hydraulic cammed FE engines and 385 series engines.
