Suits original Ford con rods only.Installation instructions:
Make sure that there is an adequate chamfer around the top of the connecting rod bolt hole to clear the radius under the head of the bolt.
Use ARP Ultra-Torque Fastener Assembly Lubricant to lubricate the threads of the bolt and under the head of the bolt. Then install the bolts and tighten them hand tight.
ARP recommends using the STRETCH METHOD when tightening the bolts. Following the instructions for using a stretch gauge, Stretch the bolts to 0.0065"-0.0070".
If you do not have a stretch gauge, torque the bolts to 45ft-lbs using ARP Ultra-Torque Fastener Assembly Lubricant.
A log should be kept on the original non-torqued length of each bolt. Bolts that have any permanent deformation or have increased in non-torqued length by more than 0.001" should be replaced.Ford Cosworth YB 16v Turbo
