Moving on to prepping the rods...

I had Ollies recondition the rods and resize the big end with ARP rod bolts. Need to break them down and give them a good cleaning...



I am using the "stretch" method for the rod bolts instead of relying on a torque value.
And, I've discovered that there are several differing techniques to measuring. Taking inspiration from Tony's post (https://forums.pelicanparts.com/911-engine-rebuilding-forum/1070821-stretch-gauge-beginner-question.html#post10994234), I came up with my own technique...

I've decided to set the dial indicator to a known value of 2.750 inches by using two gauge blocks. This will allow me to measure and record the pre-stretched length with a repeatable method.



Using this bolt as an example, it measured 0.009" from the baseline of 2.750", so the length is 2.759". When I go to install the rods, I can just add the stretch value to each bolt's original value. For example, 0.009" + 0.0095" = 0.0185 on the gauge.



On to cleaning...
