Re: EAGLE RODS (mec. pedri)
All I know is that they have a 3/8 12 piont head on them

don't use a torque wrench, use a stretch gauge. I just did mine a couple of days ago. The instructions that came with my Eagle rods recommends .005" to .0059" stretch for the arp2000 bolts (3/8"). I just gave them .006" and called it a day. I checked my oil clearances with plastigauge and they were all within spec. Break-away torque after I completed the entire assembly was 8.3 lbft, rotational torque was about 6 lbft

Well i hate to say it but dont expect that thing to last very long. The Specs say .005-.0059, by going to .006 you may have now overstretched the rod bolt and thats not a very good thing. I would take one of the bolts back out and check the free length to see if it is the same as it was before you started. If you went to .0065 or more i would throw the bolts away.

Re: (beaver)
Guys, you are being silly.
ARP's own stretch gauge doesn't have .0001" resolution, trust me, .0001" will not make, or break this situation.
Ofcourse, being **** I checked 3 of the bolts after stretching to .006 and all 3 were at zero stretch just as they were before being stretched. I also checked what the stretch was with ARP's recommended torque value, and I was within that spec as well.
If anyone here has any quantitative data that shows rod bolt failure, or any other failure for being .0001" outside a spec (that you know has a sigma value calculated into it), please feel free to post your results.

Doesn't ARP/Eagle recommend using the moly lube they provide to achive the correct tq specs? They recommend using the strectch method if you are using anything other than the moly lube they provide.

Yes. ARP's hardware comes with their bolt lube.

Thats fine if they checked out ok, im just saying its not a very good idea to torque past the specs. Its just that almost all of rod bolt failures come from either being understretched or overstretched. I just wanted to give you a heads up incase you have a failure down the road. Sounds like you will be ok with that spec though.

Re: (beaver)
You guys do realize that the poster said he has a rod bolt with a 3/8" 12 point head? That means it has a 5/16" diameter and has a torque spec of like 28lbs. Not sure of the stretch specs on that bolt.

Re: (Tooned)
So then I need to TQ with moly lube to 28lbs I just noticed on the GSR the stock rod bolt tq spec is 33lbs but with the eagle arp 2000 they are 28lbs right... thanks

ARP recommends using a stretch gauge because this method actually tells you more about physical attributes of the fastener itself, whereas using a torque wrench tells you nothing about what the fastener is doing.
And just to shut the rest of you nitwits up, ARP specifies that a fastener must be .001" over-stretched to be considered suspect...NOT .0001" like I did with mine..

and you sure dont know who Larry is...
hes a very knowledgeable guy with many years of experience and many motors making plenty power wich are reliable
hes no guy who started doing this last year
i have personally talked to him, and i will back him up anyday

There is no comparison between an oem bolt and the ARP.
BTW, if you torque any ARP rod bolt to more than 20% over it's recommended torque, you have stretched the bolt beyond it's capacity and it must be replaced. Larry is right.

Like i said do what you will, it is your motor. Im just saying its not a good idea to go past the specs, thats why they have specs.
Good luck with the build JLHDOHC
