With the moly lube, you're looking at aroung 65-70 ft lbs to get .006" stretch. USE A STRETCH GAUGE.

machine shop tom - does this imply that I should be putting moly on the main cap bolts then - currently it's engine oil only and 65/75 lbs

If you are using ARP bolts or studs, use their specs. If you are using stock bolts, use oil and torque to stock specs.
