Will these work with Eagle forged 5140 steel "SIR" I-Beam rods. They have a 2.125 rod journal as well.

Your Eagle rods will work fine with this. However depending on how you plan to use your 408" you might want to consider upgrade to a set of Molnar Technologies 4340 H-beam rods to

go with this fine quality crankshaft. [FOR SALE] - Molnar Technologies 6.123" 273, 318, 340, 360 4340 H-Beam Connecting Rods
