[QUOTE="6.4f350, post: 1377687, member: 20253"] Smaller journal will give you lower bearing speed, but if you're not doing a crazy build I don't know that it would be worth it since I haven't heard of many rod bearing failures on stockish RPM motors. Engine builders always have tricks up their sleeves and the ones doing crazy stuff that doesn't seem to make sense are usually ahead of everyone else though. For a "normal" 6-700hp build delipped OEM or IH pistons will work fine, many people have run them for a long time and they're proven. [/QUOTE]
