Ok i know the head needs to be torqued down to 75 l/bs right? So should I torque the rod bolts and the main bolts still to what the tsrm says or do they need to be torqued more to?
Torque question?

If your using ARP's torque to their spec with the supplied Moly lube. Which is 95 ft lbs with use of the moly lube. Rod bolts are meant to be used once, once they stretch they are supposed to act like a spring to keep tension on it. Especially after a rodknock if you get the rods re sized and use undersize bearings the bolts will fail because of the heat that was applied to them with no lubrication.. We just had a Fully built motor fail in our track car due to being in a rush for an event and just resizing the rods and putting it back together. Now it shot a rod out the block because the bolts let go, Destroyed the crower rods as well as the Supertech pistons.. And block and head for that matter.

OUCH!!! Ok cool that's for that info. Also got the motor out today in 3 hours not to bad for the first haha.
^^^ I thought you could to. But I'm going with new just to be safe. Like devin said I'd rather be safe then sry.
There is not a single torque to yield fastener in the 7M, so yes, you can reuse them all. Rod knock or any other type of abuse (over torque for example) is a different case.
Also, last I knew ARP torque was in the 80's not 90's. It depends on which lube and which version they are, not to mention studs vs bolts.
Also also, updated stock head bolt torque is 76 ft/lbs (easy way to remember this is it's the same as the lug nuts)

My arp studs were 82ft/ibs w/ lube. That's what I thought cause you don't have to torque it in degrees.
I called ARP and they told me to torque my ARP Head Bolts (NOT STUDS) to 90ft lbs with ARP Moly lube and 130ft lbs with gear oil. They said its the same with the studs. I gave them part numbers too for the 7M

Thats what all the new ones are. The old studs were 80ft/lb. I think some old ones were 82 too.
Just read the little sheet that the ARP fasteners come with, I'd put money on not one single person in this thread being correct so far.
I've done both studs and bolts, but don't remember specifics, and speculation is very dangerous.

I bet money your wrong since i seen 2 torque sheets from arp studs and 1 posted. If you look back far enough could prolly find it.

Best answer so far if you have the sheet.
If not, call ARP. There are several different versions of both the studs and the bolts. They have varying torque specs. They will walk you through figuring out which ones you have so you can get the correct spec from them.
Ok then guys I'm pulling the arp bolts out out of my old motor and plan on reusing. So how do I know what they are or do I just guess and hope I'm right?
