That's what I thought and what ARP recommends.

Even with a torque wrench, you will still get pretty close to the target preload. Knocking in 10 minutes sounds like something else went wrong, like forgetting to reinstall the pickup tube, lol.

The only way to be 100% sure is if You had measured them before torq them and written down every bolts length and measure them now and per instructions if any bolt has stretched .001 , replace that bolt meaning the set unless anyone knows where to obtain single ARP fasteners .

That info is wrong:

134-6006

234-6301

If you need kit instructions, to include torque values, all you have to do is go to arp-bolts.com and enter in the PN for your kit and it gives you the instructions. It's very easy and very simple.

How do you re-size the connecting rod? What is the precedure for that?

You just hone it out ~.002" larger and use a bearing meant for the larger bore.

So, this is not a simple DIY project then. It involves machine shop labor and new bearings. No wonder so many people have mixed results with this mod.. So by the time you account for the new bolts, machine shop labor, trip expenses to and from the machine shop, new bearings, etc. How much are you saving vs buying new rods that already have ARP bolts included?

No, it has to go to a machine shop.

It's cheaper than using an aftermarket rod. The cheapest option I know of is a Scat I Beam and they only have a press fit pin if you stay with the stock size .943" pin. With the press fit pin, you're still having to use a machine shop to hang the rods and pistons.

Scat also has the same I Beam rods with a .927" pin, but the pistons are typically more expensive once you go that route.
