Which connecting rods to use
Its a dollars and cents thing. Press off the old pistons, disassemble, clean, magnaflux, polish beams, cut cap and rod, install new ARP bolts, resize, weight match/balance. This all costs $ at the shop. Now you've got a set of weaker forgings with an unknown fatigue history. Heavier than any I-beam aftermarket rod, pain in the *** press fit small ends, and inconsistent lengths.
Now compare that to a set of after market rods. Its false economy IMO.
