Ford Engine Bolt Torque Chart
Bolt Torque Spec Chart for Ford Engines
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 after-market performance bolts like ARP's, you should follow the recommended torque specifications.

Hello vienotkelly: The correct Main bolt torque is 42 foot pounds. The connecting rods torque to 29 foot pounds. The torque sequence for the head bolts and the correct way to tighten the bolts are attached to this reply. Thak You for using FixYa. Roger
