OEM Rocker Arm Side Play

Frankly, to my eyes..... the factory rockers are much nicer.

The Melling rockers have a bunch of added mass in areas that do nothing for strength, but are definitely adding to the moment of inertia.

If the rest of the factory rockers looked as good as that one...... they’d have gone right on the new build.


I noticed that too, not overly concerned that much, but a valid point. I have wondered if these rockers are stamped for both small and big block, the same overall size but the pushrod dimpling is positioned differently depending? Awfully large flat area for that:
