Aluminum rods for sure on blown injected engines. The rod is able to absorbe the extreme shock and rattle the piston is battling with and keeps the motor alive. A steel rod like that will usually rip off at the crank side.
Several people make good aluminum rods, BME, Brooks, grp... and so one, but dont buy the cheap ones from jegs. lol. Talk to some of these guys and tell them what hp you are trying to achieve and get back to us!
Hope this helps!
