Interesting read on fatigue. 300M steel seems to have a fatigue limit >4 times higher than aluminum (with 10^8 cycles or so), so in theory 300M rods built to the same strength would be lighter. Damn.
I think for lower rpm street cars the stresses would be low enough and the compressive forces would be comparatively greater so aluminum rods could outlast most of the other engine parts. I think aluminum is probably cheaper than say 300M steel so we might see it in street cars someday.
BTW WoW, the red lettering is quite menacing
