at that price, I would assume it is a cast crank with I-Beam rods???? Probably ok for a street engine, if you planning on some racing or high rpm might want to consider at least a forged crank...H-beam rods are stronger, too.... Whatever you get, it is well worth the extra $$$$ to have the rotating assembly balanced. Check all your clearances closely, just because it's all brand new parts, no guarantee they were made to spec....
