70 ft/lbs. Did a lot of searching myself when installing mine.

You can always call ARP for verification, they are very helpful.

60ftlb with moly lube.
are you checking your mains clearances with the new studs?
beware of just chucking studs in without checking clearance change!

Na it's a new motor and it's been line honed.... I was checking main bearing clearance and numbers were .0015"

Was it line honed with the ARPs torqued to 70ft/lbs? That will be an issue if not, you can't just throw in a set of main studs in a block that was line honed for the stock bolts and expect the bearing clearances to be the same and the crank not to bind.

That's a good point! I didn't think of that so I asked and they were torqued to 45.... Is it ok to go tighter if the clearances are all the same and consistent? Those number I got were using oil for assembly I'm planning to torque to 60ft/lb

Also, no, it was line honed with this set of arps...... I just didn't know they had torqued them down to 45ftlb...... However I will torque down to 60 with arp lube

I would torque the main girdle down to 60ft/lbs and re-check the clearances.

check the clearance @ 45ftlbs, then recheck them at 60ftlbs.

There is no point getting it line honed @ 45ftlbs if you're going to torque them to 60ftlbs, it defeats the whole point of doing the line honing.
