BTW when your selecting a rotateing assembly, 5.7" rood tend to be a good choice on a 383 but 6" rods can add a slight amout of hp due to lower ring drag,lower piston weight,longer dwell time and a more efficient rod angle during the power stroke, yes the differance is very minor but it is there, so why not take advantage of the info?
yeah, the lower oil ring goes thru the upper edge of the pin hole but thats not a problem with the better ring/piston designs

On an average engine build-up this (I BEAM STYLE ROD) (top)requires a good deal MORE clearance work than

this (H STYLE ROD)(bottom)
and (I BEAM) style rods frequently require SMALL BASE CIRCLE CAMS FOR CLEARANCE, while (H) style rods have slightly greater clearance, (something to think about when buying parts/building a stroker engine (YES YOU STILL MIGHT NEED A SMALL BASE CAM AND CLEARANCE KNOTCHES WITH A (H) STYLE ROD but the chances are much better that the clearance work will be minimal. SOME (H) style rods tend to be slightly lighter in weight, making ballance work easier,also! :grin:
