A pushrod selection consideration is the tuning effect of size, length, and stiffness of the components in the valve train.

Two spectacular collections of antique, classic, and other interesting vehicles and memorabilia within a couple of miles of each other, either of which is worth the trip.
Lessons learned from one engine are adapted and applied to the next and your process, and hopefully your percentage of successful outcomes increases as your skill and knowledge improves.
There are only a few basic rules to engine performance, just a few places where improvements are needed to increase output and reliability. A good first step to increase performance is to begin by increasing the efficiency of the air pump by decreasing inlet and outlet restrictions and by maximizing cylinder head flow.
