Read an article, these rods use bolt stretch instead of torque... Another article said to torque to 70 ft-lbs. I don't have a rod bolt stretch gauge, how many ft-lbs are recommended? Opinions?

 

My engine builder wouldn't torque any rod bolt ever again. Thats what he told me, so i would buy one if you could...

 

Wouldn't it make a difference since the rods have been used? All I know is these are some big *** rod bolts!

 

Not all Torque wrenches read the same.
Thats why to use a stretch guage.
ARP recomends .0045" - .005"

 

I'll see if I can round one up... Thanks for your help!

 

Gonna pick up a stretch gauge... Is that the actual spec for those rod bolts? 4.5-5 thousandths of an inch? Only problem I see, is that these rods were already used... Doesn't affect stretch and strength?

 

Once the rod bolts are torqued,there done,they are stretched,you will have to replace them for this type of procedure.

 

I torqued mine to 75ft-lbs. They had already been stretched when they were installed the first time so there is no way of knowing what the proper torque is. I heard 70-75 ft-lbs if torquing after stretched is about right. You don't have to get new bolts after stretching. When checking/setting bearing clearances, the bolt bolts are tightened and loosened many times. 810 miles on the motor and my rods are still in one piece.

 

I would definitely trust you.. If it was going to let go, it would've done it by now! LOL I agree, I was going to shoot for 70 ft lbs... Thanks for the advice guys, and thanks for chiming in Ferocity, always good to hear from you!
