can some elaborate more on rod resizing
Specifically after the process of installing ARP rod bolts.
Is it to bring the big end bearing areas back to being perfectly round again?
Would this process normally require a change in bearing sizes?
There are some threads on here about resizing but didn't go into detail about the process.
thanks

Re: can some elaborate more on rod resizing
I'm not a machinist so hopefully they can confirm or even correct me in my understanding.
When you swap rod bolts, ARP recommends larger torque values to get the proper stretch. Or you use a stretch gauge and it results it more torque on the new stronger bolts.
This extra pressure distorts the big end bores and that is why you are to line hone the big ends with the new bolts in place.
You are basically doing what the factory originally did with their stock bolts. Line hone after torque to make sure the bore is perfectly round for the bearings.

Changing from bolts to studs or anything that can affect how the rod cap sits, a "resize" is recommended,. Just like adding ARP main studs to a block requires a block line hone. The slightest change in rod fastener torque can distort the bore.
Also be careful not to resize the rods too much as the bigger you go, the more bearing crush you lose. I think something like .001" max was acceptable.
