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 discredited that myth.
The BME Rod has great durability in high-end, high-power, street/strip or hot street engines because it is die-forged, rather than cut out of a plate. Bill Miller Engineering's unique, aluminum alloy further enhances fatigue strength such that the durability of BME Rod rivals that of many forged steel rods and exceeds that of a few.
"In a hot street application, using the aluminum rod is a no brainer," BME President, Bill Miller, said in an interview with an automotive magazine. "I don't know how the myth that aluminum rods can't be used on the street got started, but I'll guess that, back in the 60s and early-70s, they weren't making them using the process we're using today. With the material we've got and they way we manufacture the connecting rods, they'll live a couple hundred thousand miles on the street because a street application is, for the most part, low load. Our basic Aluminum Rod is made for an 1000-hp, 10,000 rpm race engine. The design criteria for the connecting rod is way overkill for what it's going see on the street. We been running aluminum rods on the street for more than two decades."
