These
specs are for stock-type bolts with light engine oil applied to the
threads and the underside of the bolt head. Moly and other lubes offer
reduced friction and increased bolt tension, which will affect the
torque figure. If you use aftermarket performance bolts like ARP's, you
should follow the recommended torque specification. Please note that some specifications are in
inch-pounds rather
than foot-pounds. Read the charts carefully to prevent broken
bolts due to excessive torquing. |
