Stroker Combo Questions

My 500 B motor (400 block) uses a 4.15 crank and 6.76 (440 length) rods with chrysler big ends, for a rod stroke ratio of 1.63. The pistons however are very short, but also very light (500 grams or so). Not sure the comp height, but the oil ring is in the pin boss, and I have issues with piston slap. If I had it to do over I would have used a shorter (400 length) rod for more piston skirt. I needed to do very minor grinding for rod clearance at the bottom of the bores and on the oil pickup boss. If you use a chevy rod length and big end you may not need to clearance anything. I was stubborn, and wanted chrysler spec rods. The 440 gives you a lot more room to play with rod/piston combos.
