Really no reason to worry about rod side clearances, the oil is metered out through the annular space between bearing and journal. The side clearances on a stock Chrysler setup are much larger and being downstream, contribute zero to oil control.

If I had all the money in the world I'd go with Crower or Oliver. It'd probably be a custom rod to match your desires. Crower can make any rod you want, just tell them what and throw money at them.
