EDIT 2 - More info http://www.dragzine.com/tech-stories...yths-with-grp/

Moral of the stories are if you want long life, don't go aluminum.
Largest problem is Case clearance, The ROD Journal is already smaller to clear the case and the Aluminum rods are bulky to add strength. Then again we are not making 1000+HP

Billet is different than forged though

"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."
