Default torque specs for 949 rods

im not sure where i should even start to look for the torque specs for the ARP rod bolts on my 949 rods so i,ll start by asking here
I,ll call 949 tmrw but wanted to ask now to see if i can get an answer faster

Please keep in mind these rods DID NOT come with the newer ARP 2000 bolts. Not sure which type of arp bolts since there are no numbers on em.

There is a stretch spec. .005-.007 IIRC, but check with Emilio or Belfab.

If they were shipped after about March 1st, they were M-Tuned rods and had 8740 rod bolts. We stopped carrying anything from Belfab in February.

Not sure which length bolt. Each 3/8" 8740 ARP rod bolt with this type head has different specs. Three methods to arrive at correct clamp load. Torque, stretch and angle. Stretch and torque specs included in sheet with rods.

I'll post it when I get in tomorrow

Correct... and damn near every rod I've worked with has been in that range.
