LA Engine – 273, 318, 340, 360
Torque specifications are for stock factory type bolts with light engine oil applied to the threads and the underside of the bolt head. Other lubrications offer reduced friction and increased bolt tension, and will affect the torque figure. If using aftermarket performance bolts, you should follow the recommended torque specifications of the aftermarket bolts.
* Please Note: Some specifications listed below are in inch-pounds rather than foot-pounds. Over torquing will result in broken bolts.
* Torque values shown are in ft/lbs unless otherwise noted – Follow factory torque sequence.
