ARP rod bolt stretch DIMENSION for a 3.2
Can't find my datasheet for my 3.2 for the proper rod bolt stretch.
Rods are hung, ready for bolt stretch. Anyone know? TIA!!!! ![]()

Check this thread
from the thread "As all that I was checking was the required torque to get the .0100 - .0105 stretch"

Obviously check with ARP and the part number etc. I guess you can torque if you don't have the stretch gauge

That stretch spec is for 10mm bolts. You should have 9mm no?

Yes, the 3.2 should be 9mm. Here is the correct doc for the 9mm bolts:

I went .01025 to split the difference accounting for error.

What are you using to measure to .00005"?
