One reason , 3.79" cranks dont sell like they should is because they don't make the crank journals/pin to the size of thestock mopar rod(2.125") instead they machine it too 2.1" requiring a Chevy LS bearing/ 1997-2013 / clevite cb663p.., which is also a bit thinner. And the piston pin is a Chevy size on the 6" or 6.125" Chevy LS rods. Hence to use a Mopar rod and stock pistons, machine the moparRod on the big end thinner to Chevy witdth. And find correct Size bearings, 2.125", or make your own if you dare to be criticize, see attached photos for the correct material and cut to size and fit to the backside of of the above LS bearing, I don't suggest using valve grinding compound to cause
