This
website is focused on dispelling the myths and rhetoric about rocker geometry.
It's written by an engine builder for engine builders, and relies on results
from you testing this "theory" yourself, rather than saturated advertising that
tells you nothing. No matter who's rockers you use, if you study both the
"Installed Geometry" and "Design Geometry" principles here, developed and
Patented by Jim Miller, then at the very least you will get the most from
whatever brand rocker you're using.
Precision Geometry was developed
for roller rocker arms by
Jim Miller in 1973 and
Patented
in 1982 to define
MID-LIFT
geometry
as the standard for any serious high performance OHV engine. For over 20
years MID-LIFT geometry has been a closely held secret by competitors in
the know, as well as a major point of contention for the well advertised
"name brand" companies who offer less efficient designs.
These well known companies spend lots of money on advertising,
so when top name magazines finally get around to correcting their prior mistakes
on rocker geometry, it's no surprise MID-LIFT is dismissed as “theory,”
or as only one idea of many being used, implying there are equally good options.
An example of this is by Circle Track magazine. (See:

POLITICS)
