Rod Bolt torque

ARP will normally give you a spec IF the original manufacturer of the rod gives one, ARP will have it. If the original manufacturer of the rod does not give a spec (for example, Eagle does not give a stretch spec on some of the SIR rods) then ARP will not have the spec to give.

If ARP does not have it, then you might try a vendor who used to sell C&A products. They may have an old catalog. Normally I save those. I also save the spec sheet on parts, but I don't have anything on C&A rods.

If you do not know what they were originally torqued or stretched to, I strongly suggest that whatever spec you decide to use, you torque them up in a vise outside the engine first, and have them checked for size and roundness, just to make sure you don't create a problem.
