I was involved in a 4.100 stroke Eagle crank with 6.125" rods and JE pistons ~ 2 years ago and had a problem with the counter weight hitting right under the wrist pin on the piston. Also when the piston would rock at top dead center, the skirt would hit the counterweight as well. It resulted in ~3 engine tear downs because we couldn't find the problem of the knocking. You had to physically push the piston skirt to get it to rock enough to interfere like it was running. Oh those were nightmare days. 
Maybe the piston and crank companies have their **** together by now on the longer than 4.00" strokes.
