625 bolts
we just lost a motor and the same was the issue, the head of 2 nuts were in the pan. They were whatever bolts that comes with the Manley "Turbo Tuffs"
Motor made 809whp.

Re: rod bolts
I have arp2000 in engines making 300+ per cylinder and they aren't breaking..
I can't imagine you having issues at only 150 per hole..
Most guys around here like to instantly blame the part or particular brands before realizing what the issue's are first..

Re: rod bolts
Not sure what your issue is as it's hard to without having parts in front of you...
Do you have a clearance problem? What are they being torqued at? Are they new? Etc.. Etc..

Re: rod bolts
well here it is i came out the water box and taptaptap so shut it down put it on the trailor
went home dropped the pan and halfe the rod bolt is in the pan along with a good chunk of darton sleeve, and block peices.
the connector was still on the rod with the other bolt still torqued to spec. I did mention it was stretched due to heat the broken bolt was bluish in color, and skinny near the break doesnt this mean heated and stetched to the point of breakage.
if im correct it sounds like i know the issue, but i may be wrong

Re: rod bolts
It sounds like you have a oil lubrication problem on that crank journal where it stretched. It's very easy to stretch and bend metal when it is heated excessively. Could have clogged oil gully on the crank to rod oiling hole.
