Glad I'm not the only one who's had trouble with the rod bolt stretch measurement. grin I tried to do that w/ my hemi when I built it in 2006 w/ Oliver rods. Had a heck of a time getting consistent measurements...real sensitive. Ended up just torqueing them to Oliver's spec. That was 2006 and I've beat on this motor pretty good w/ no issues. That stretch gauge hasn't left my toolbox since. twocents
