Reuse of stock con rods? 
Reuse of stock con rods?
They say there good to 500+ i belive. anyone correct me if im wrong.
i reused mine and havnt had any issues. the rod bolts are the weak link. Buy ARP's and forget about it! You can run it to the moon........almost.

They are the "cracked" type. I was under the impression that you could not reuse them. I never really heard of anyone doing a rebuild with the stock rods though. I was just curious...
I am doing a build right now on mine, reusing rods and pistons... Just make sure to keep you rods and caps together, yes they are cracked which means the rods and caps have to go back the same way they came apart.
Number your rods and caps so you know they will go together the right way. I also bought the Arp 2000 bolts from what i here they actually strenthen the rod, dont know if its true but i do know rod bolts are a problem and the Arp's should help out alot.

If it spun a rod bearing then you can not re-use the rod. Because they are a cracked rod they can't be resized to correct damage caused by the bearing spinning.Maybe that's what someone told you?

Verdad Gallardo why wouldnt you be able to reuse the rod? why if the the crank is replaced just throw another stock rod bearing in it bolt it up and your good to go arent you? Im no engine builder
Because the bearing spinning in the rod will open up the inside diameter and the heat generated by the friction distorts the shape. It is common practice to machine the mating surface of rod and cap then hone the ID true. But because a cracked rod does not have a machined surface where the rod and cap meet this can't be done.

you learn something new everyday! 
this is not true at all bro. not being a dick but they CAN be resized/honed depending on how out of round it is. an oversize thickness bearing is available. do a search on here youll find out.
It would be better to get one new rod than to hone them all to accept oversize bearings.
You could also buy a brand new set of stock length (6.098) Scat forged I beams (either .945 or .927 pins) from speed inc for $300. They will be way stronger than a stock rod and already come with ARP bolts.
If your stock then you should be okay. But if your putting some kind of power here is what happen to mine. Rods had 99k tho.
Lol well that was with a g5x4 cam, ls6 heads, headers and at 6,500k untuned... Yeah stupid of me
i learned my lesson haha.

i learned my lesson haha. thats true...but like he said....he spun one. its cost effective to resize. sometimes you dont even have to use a thicker bearing shell. they can machine just enough off the cap faces that they still match up and resize the rod depending on how non-concentric the journal is. its done all the time.
These LS1 rods are NOT like the old sbc/bbc rods that you can re-size for a rebuild. I'm sure that it would be better to replace the rod and or rods. Thanks for the clarification, 5.3LJimmy.
I'm not trying to be argumentative here, but you can not machine the faces of the mating surfaces on a cracked rod. There are no dowels to align the cap, it is held true by the jagged surface left by the cracking process. Machining the mating surfaces will remove the fractured surface and allow the cap to move around on the bolts.
