i probably have 5000HARD miles on these bolts. i didn't resize and they are the standard arp rod bolts. i did the torqe and loosen 3 times trick and that is it. when i was nitrous only i was shifting above 6800 but now with the turbo i am shifting at 6400max.

sounds like a good idea to me

just bring this to the top since i found it useful

So....... I'm left unsure of things here. I ordered ARP rod bolts yesterday. Are they going to cause a problem? I'll be shifting around 64 to 6600, with about 10lbs of boost I'd imagine/guess. Do I need the ARP's or should I leave well enough alone? Opinions needed.

This is exactly correct. The LSx engines with the bolt style rod bolt and not the pressed in stud and nut do not require resizing. As a matter of fact the rods can not be resized. They are powdered metal and are made and machined as one piece and then "cracked" or broken to seperate the rod at the journal. That is why the rod looks like it was broken, it was. To resize they actually have to grind the cap and rod mating surface(or just the cap) to make the diameter smaller then re-hone the rod to correct size.
Howards Cams actually sells aftermarket racing powdered metal cracked rods for small and BBC. They are very strong.

Well...... I know I feel better. I was concerned about the process to follow when I go to install the new ARP rod bolts. It sounds like I just remove the old bolts and install the new?

Thanks, Jim

I know of atleast 3 people out at the local track running arp rod bolts with 700+ hp in LS1's so I would imagine that could be considered very strong for a stock part.
