I feel our mopars have some rod bearing starvation issues. Narrow full grooves help fix that IMO.

Sure a 3/4 or half groove bearing might be better for the Crank itself. But I feel the Narrow full grooves are fine. Its more important to feed the rods then worry about a little loss surface area on the bearing for the crank.

So for me its the Narrow Full groove bearing all the way.
