With the weight of the air/fuel charge, it should still be rushing in after the piston is at BDC on its way up. It gets way more complex than that simple, “What it should be doing” statement.

Funny Wyrmrider mention Harvey Crane.

Your idea of a bigger lift bore to use a greater diameter roller wheel is a bit beyond normal guys wallets and plans I think. Not knocking the idea. I just wonder where it stops?

Wyrmrider, why did you short explain the pushrod length issue and the rocker tip description?
IE;

Where the tip should be to start.
Direction of travel on to long or short of a pushrod.
Etc....
