What torque should SCAT connecting rod bolts be tightened to?

It depends on the bolt: 5/16" x 1.500" ARP 2000 cap screws take 26 ft./lb; 3/8" bolts take 45–50 ft./lb; 7/16" bolts take 63–70 ft./lb, all with ARP moly lube. Each has a not-to-exceed stretch spec from .0046" to .0063".

What lubricant does SCAT specify for rod bolt installation?

Apply ARP Molylube to the threads and under the head of each bolt; all torque values in the table are given with ARP moly.

Can I use the rod bolts to pull the caps into position?

No. The instructions state in capitals: DO NOT USE BOLTS TO PULL CAPS INTO POSITION. Tap the cap into place before installing the bolts.

How do I match rod caps to the correct rod?

Each rod is numbered and MUST be assembled with the same number on cap and beam.

What is the torque and stretch spec for 7/16" x 1.600" ARP 2000 cap screws?

70 ft./lb with ARP moly, not to exceed .0062" stretch.

This document is a SCAT Crankshafts & Connecting Rods installation instruction sheet (an aftermarket parts insert, not a Ford factory document). It provides a four-step procedure for installing SCAT connecting rods: (1) disassemble and thoroughly clean the rods including bolt and beam threads to remove rust preventative; (2) apply ARP Molylube to the threads and under each bolt head; (3) align cap and beam and tap into place before installing bolts — the caps must never be pulled into position with the bolts, and each numbered cap must be matched to the beam with the same number; and (4) sequentially torque the bolts to the specified torque without exceeding the maximum bolt-stretch specification. A torque table lists ten rod bolt types (5/16", 3/8", and 7/16" ARP 2000, ARP 8740, ARP Wave Loc, and SCAT 2001 cap screws) with recommended torque values from 26 to 70 ft./lb using ARP moly lube, along with corresponding not-to-exceed stretch values ranging from .0046" to .0063". The sheet closes with SCAT's customer service hours (9:00 a.m.–4:30 p.m. PST, Monday–Friday) and phone number, (310) 370-5501, and is marked "OVER" indicating additional content on the reverse side.
