I have a set of H beam forged rods for my B18C1 build, and they come with ARP 2000 rod bolts, a 12 point 7/16" socket fits the head. I don't have a sheet telling me the torq specs. Any ideas?

Thanks

I think that describes a nut and bolt. Mine is just a bolt with a threaded rod.

Ok, but the torque spec is the same.

Here's what I have done in the past.

1) torque rod one bolt to 20 ft-lbs.
2) torque opposing rod bolt on the same rod 20 ft-lbs.
This will get the rod cap seated evenly on the rod.
3) torque the rod bolt from step 1 to 50 ft-lbs. My torque wrench is not super accurate so I tend to go 2 to 3 ft-lbs higher.
4) torque the opposing rod bolt to 50 ft-lbs or slightly higher depending on the accuracy of your torque wrench.

Check with rod manufacturer. If you over torque them you could send them out of round.

V-SPEC 1

Normally they are torque around 50 ft lbs using motor oil. I hope that helps.

I set them @ 43ftlbs using ARP lube. Im gonna call APR today and see how close I am.

You need to speak to who ever you brought your rods off. When they were honed, they was honed at a certain ftlbs. Don't make the mistake i made a few years back.

Yep, we did hone them all at 43ft lbs, I took my clearance reading at the same torq and my specs were right on .017 to .018

I'd torque them to that. See what ARP say anyway.
