Bolt Torques

[Large Arbor]

Anyone know what the bolt torque is on the harmonic balancer to crank? Also if you know the torque for the intake bolts and head bolts to an aluminum block Shelby that would be helpful. I am just checking sure everything it tight and nothing is loosening.

If it's an ARP balancer bolt, I usually torque them at around 130.

Head studs usually get 90 lb-ft on an aluminum block. I don't really torque intake bolts. I have a calibrated hand and 9/16" wrench. You'd be able to tell if they were loose if you put a wrench on it.

For us non pros without calibrated hands, I believe intake bolts should be torqued to 22-25 ft-lb. That is for aluminum block, heads, and intake.
