I'm probably wrong here but my last experience with stock powdered metal cracked cap rods was the rod bolts cannot be replaced because they are integral to the cap alignment. Has that changed?

I believe that the rod bolts can be upgraded but the rod caps cannot be swapped as you mentioned.

ARP Bolts are an upgrade but the caps can not be changed or interchanged. The carrillo rods are stronger, but better yet they are lighter than the stock rods. The Original rods vary in weight by several grams. My set of Carrillo rod were within .5 grams of each other.

As a low cost (huge..) improvement, you can only install the ARP studs and rebalance the OEM rods...
Of course, being there considering the Carrillo rods would be a 'huge step up' 😁

Honestly, originally I budget on my engine rebuilt (using LN Nickies) a set of Carrillo's along with a head work from Hoffman Automotive

However, it is difficult to draw the line, that is the reason I said that you could 'only replace' the conrod bolts with ARP's to keep te cost down..
