Not Ranked
If the engine isn't in anything--I'd suggest taking a rod out and weigh it--alum is 1/3 the weight of steel, but the aluminum rod is pretty bulky and maybe not that much different than the steel rods weight- you might be able to get some steel rods nearly the same weight--the big difference would be if the aluminum rods are a special length requiring an expensive replacement--if the engine has been built up for some form of racing, does it really meet your needs? I will go thru some of my balance cards to see aprox what the weight difference is and post back here
