Rod Bolt torque

[Glenn Briglio]

C&A is out of business. Try recalling ARP and crying on their shoulder.

[Alan Roehrich]

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.

ARP on line. Page 24, 25, 26 gives bolt torque specs.
Also at the top of page 33 it gives the procedure for calling ARP TECH and the tech line numbers of some rod mfg's that use ARP fasteners.

If they are old and you don't know their torque history it might be safe to change them.
It's just a thought, but someone else could have used the wrong torque spec in their life cycle. ... ??

Cause you got addicted to drag racing and you didn't start with $3 million.

What JimR said.. we have an addiction / passion to do what we do, we are smart, have common sense, and the ability to direct others on how to do this stuff,... unfortunatelly, they don't teach this at college, so we cant pay for a degree so we can charge for all the hours we give free info for the knowledge we have aquired over the years by bumbeling thru life building engines and learning from our mistakes and failures...sorry for rambling Alan, thats why we ain't rich... I'm gonna get a 900 number!

And Adger, I haven't forgotton about you

Thanks Al,

That is the rod that is in this engine. I knew someone would have an old C/A catalog out there. Thats the great thing about this site We all try to help each other out. Thanks for taking the time to look for the information that I needed.
