I have a LS9 Short block and want to change the mains bolts to studs.Has anyone changed out their Factory Main Bolts and Replacing them with ARPs without line honing. Can you change them one at a time. Any help is greatly appreciated. Also want to do the connecting rods. Stay Safe

I've done the Rod bolts a couple of times on cracked rod LS motors no issues at all still running many years of abuse. Im not sure if those LS9 rods are cracked being Ti I think they are machined in which case a bolt swap without machine work sounds risky, which you can double down that statement for swapping studs into the mains as they are also machined. Stock hardware takes a LOT of hard running though, I cant see why you would need to swap these out?

i did a test with a digital Snap On torque wrench when I built my LS2 and found that the stock TTY main bolts will lose a lot of clamping force if you torque them to spec more than once. If you are setting up your bottom end and having to take the crank in/out. Plan on a fresh set of stock bolts for the final assembly. By the time you buy those, spend a few more, buy the ARP's, pay for the align hone and get it over with. There are no other options if you are doing it right.
