You can also put a longer rod into the RB and the crankshaft is a little stronger.

Andy,
Why is the RB crank stronger? For the same stroke, the low deck will have less journal overlap making it stronger (2.750 vs 2.625" mains).

I have my low deck blocks align bored for 440 bearings and aluminum main caps. This gives the better 440 bearing choices, and cushions the factory block somewhat. And my 4.250" stroke (nice) has 2.200 rod journals to help overlap vs the MOPAR 2.375"
