i reassembled my bottom end on my LM7.. i checked the post Torque to angle applied torque.. main cap lowest Newton Meters torque applied was 42.. under 30 Ft Lbs.. rod bolts where 52 to 64 so just over 30 to 47 ft lbs.. i went back inside and ordered studs and rod bolts..did not feel comfortable continuing to put it back together with those as final measurements.
I didn't resize my gen4 ls rods using the same arp bolts and pushed it to 930hp no problems. If the manufacturer didn't recommend a rode hone why should we worry
I just put mine in last night and called arp to be sure I tightened them to the right spec. The guy said I should go back take them all off and take the sleeve out of each one then put them back. I am not sure why I need to? I mean they torqued to 15 psi no problems they were a little tight to get the bolts in but they threaded in and they tightened down I can't understand why it is a problem?
ARP says the BEST method is a stretch gauge BUT IF YOU DO NOT HAVE ONE, torque to X ft lbs. i have never had an issue with ARP fasteners and their torque specification over their stretch spec. ( i did a full ARP stud and Eagle rod's which uses ARP fasteners on an eagle talon 4G63 build never had a failure from the fasteners)
Do you have to take the sleeve out? I just did mine last night and I didn't take the sleeve out I just threaded the old ones out and put the new arp bolts back in.
I just did mine and the arp bolts are like 1/4 inch longer and have a shoulder on them too. I don't know about this resizing thing u just put them in lol. I did call to make sure they were right and they said yes.

I didn’t re size my rods ether , haven’t start it yet my question is is yours still running / any problems?
@mannysolis4588 0 issues, if you're too worried have your big end mesured before popping in the new bolts. I didn't mesure mine
@@Airman.. thanks bro for your help

@agooser26 what sleeves? Oem bolts should pullout with their sleeves
Have you had success doing this on past engines?

How the hell do you resize the rods?
Amen!

After doing two rods tonight, I'm in the house looking for the same answer.
Let me know what you found. I have mine buttoned so still haven't tried to pull anything out etc.
Are those bolts the same length or are arp a little longer?
