Torque spec for ARP rod bolts
Hey guys.
I just spent 5 hours refreshening my Forged 383 short block, which btw will be up sale soon.
I got everything else completed. I put the rod caps on and lightly snugged them, but I was using my LT1 rebuild book which gives factory torque specs. like 25 ft lbs and then 55 deg. Which is for torque to yield....
So anyways whats the torque spec for the rod bolts. if it helps (not that it should matter) its a ARP rod bolt, Eagle H beam rods on a 4340 Chromeonly steel crank. My original build sheet didnt include torque specs.
Thanks!
Any questions on the motor (serious buyer inquire only pls), PM me.

I just need to look at the bolt, the part # i was 99.9999999% sure it was on the top of the bolt, as long as it matches then I think I am in biz, otherwise I gotta call.
