When to upgrade connecting rod bolts? How much can stock connecting rod bolts handle?
If engine is bone stock and the car is a DD that will be reved to 6000-7000 rpm about %35 of the time...is it necessary to upgrade the rod bolts when rebuilding the engine?
Basically, under what circumstance should the rod bolts be upgraded?

So you're going to have to be a lot more specific as to what rpms you plan on running and tell us what year rods you have. 97-98s were weak compared to the 99+

That is a very very broad range when it comes to connecting rods. At 6000rpm, even the lousy early LS1s should last. By 7000rpm, even the beefier gen 4 rods are going to be pushed to their limits.

Its 2004.
My bad. Lemme put it this way...It will spend %35 of its daily 5 hours on the road on WOT. So lets say 6500 rpm.

yes they should... If you dont want to hone rods I would use katechs. They have never had a documented failure after install with the bearings, arp is very good when the rod is resized without that you run a risk

Every aftermarket rod bolt distorts the bore. How much? Each bore will be distorted a different amount. Enough distortion to cause a bearing failure? Depends on a ton of factors. I know some who have had good luck, and some that have lost engines. Better to play it safe OP and stay out of your bottom end for now. I'd say keep your shifting at 6500 or lower and don't worry about it.
I agree^ you should be ok at 6500. every rod bolt may distort the bore a little. I'm just going with the notion that I've never seen or heard of a Katech causing a spun bearing whereas I can't say the same for any of the arps. Katech advertises no resizing needed and clearly does deliver.
