Common Block Troque Specs.

[TurboZman]

Just got a common block that I am rebuilding. What are the bolt torque specs for the main cap bolts and the rod bolts (TII Rods)? Are they the same as the non-common block and TI Rods? The manual I have is for an 86 daytona (non-common block) Not sure if the specs are the same??? Can anyone check for me in there 89 and up manual. Thanks.

Main caps = 30 ft/lbs + 1/4 turn
Rod caps = 40 ft/lbs + 1/4 turn

Thanks for your help.

keep in mind that with these specs, the bolts are torque to yield, so they should be replaced when doing a rebuild. some people like to reuse these fasteners over, but if you are going to cheap out in a buildup, don't do it in the bottom end. or you could always do it again :\

I was going to re-use the same bolts. Why??? Anyone have problems in the past with re-used ones failing??

Don't re-use the rod bolts because can fail like this:

OUCH!!
arp's are money well spent, plus you get a re-conned rod(rod needs resized for the arp's)

Is it ok to reuse ARP rod bolts one time??

arp is not a torque to yield bolt so you can reuse but it's still not recommended. I learned that one the hard way 15 years ago on my race motor. Ford and GM have AWSOME!!!!!!! service videos on the torque to yield fastener. EVERYONE needs to watch one of these videos to understand what the purpose of the angle method is and how it puts the bolt to it's elastic limit.
