ARP2000 rod bolt torque procedure?

A long while back I was looking into the whole stretch vs tq method, found this on a chevy site, dude mixed up on a bolt size vs head bolt size.

How could one not know as posted with this pic, "It wouldnt tighten at 75 pounds"

FWIW

My Scat rods with the Arp 2000 bolts were all at almost perfect stretch at 65 ft lbs with Arp molly lube.I think 1 of the bolts was off by .0001.-Randy

I dont expect everyone to understand my chicken scratches, these were up to 63 pounds and Im pretty sure I clicked them one time at 65 as mentioned just for kicks. But I rounded down on my 63 lb numbers.

I wont use bolts over or on a freshen up.

The number 2 outter is what I could not get right so I used another new bolt.

Im sure the experts have a different or better (More Correct) way, however ive not had one come apart yet.

This was my bench copy, then I make a puter copy.

Ive read mixed things on the ARP 2000 bolts and the "proper way to install them" from an actual ft pound figure to a certain pound and then so many degrees.

I get them at .0055 and that seems to work for me.

How do others do it?????

I still use a torque wrench.... never had any issues...
I;m sure that one bolt you had would have been fine
if you torqued it... would have had the same clamping
force as the others... also I know my wrench is on
I have had it calibrated 4 times now and it still
shows good

Your very right MR P on just the TQ wrench alone, but it is a good backup to a point it seems.

I did my spray motor with a TQ wrench and no stretch check and have had no issues.

So what is one to do except do the best and try to avoid mistakes and bad parts.

Hey, Is a new TQ wrench say a Snap On and or Mac
cal. when new. Both mine are and ive been wondering if they are tested prior to sale???

I'll be honest and admit that I didn't bother using the new bolt stretch gauge I bought during my last rebuild because it seemed like a total PITA to use. I just strapped my ARP 8740s down to 65 #s (63 on Eagle's spec card + another 2 "just because") and went with it.

HOWEVER, I'll be going back through the same bottom end (and have another one that's in progress) and now plan to cross-check the stretch #s w/ the torque #s for peace of mind.

So can someone explain the process please ... do you use a torque wrench and watch the torque as well as the stretch ?? Seems to me you would have to otherwise you could theoretically have a bad bolt that would stretch the spec'd amount with only a few #s of torque !!

The problem that Ihad with the strech method, was when I received the rods with the bolts, they had already been torqued AT LEAST once, to hone the big ends of the rods. The strech method wants you to measure the bolt BEFORE being torqued, then measure as you are assembling. Or am I missing something, because I had no way of knowing what the bolts were originally torqued to, or the orig. length.
