Damn.. look at the bevel they use for the radius on the crank.. that looks big... then also. the area around the crank.. one has a much larger wall.. I bought 4 sets of Eagle H-beams YEARS ago when they first came out because they looked damn good back then... I'm still using them on all my builds
Bottom one doesnt have the clamping strength of the top one in the cap area. That smooth casting from the radius to the edge is the touching point. Also one allows oil to escape to the edges of the rod for a nice thin layer of oil to prevent side wear.
One clearly has much more detail in finish than the other. Also the pin end the bottom one looks narrow and missing the strength on the edge where the beam finishes up into the pin area.
