Urban legends abound in the gearhead community.
One is: aluminum connecting rods don't work in street engines.
Prior to the mid-'70s, that might have been true, however,
introduction of the Bill Miller Engineering Forged Aluminum
Connecting Rod in 1975 provided a glaring exception to that
myth.
BME Forged Rods
The BME Rod has good durability
in high-end, high-power, street/strip or hot
street engines because it is die-forged, rather
than cut out of an aluminum plate. Bill Miller
Engineering's unique, high-strength, aluminum
alloy further enhances fatigue strength such
that the potential durability of BME Rod rivals
that of many forged steel rods and exceeds that
of a few.
