if i recall correctly, it should be 60-65 ft. lbs. for a 7/16" rod bolt.

if they are a stock type rod with a nut that sounds close, if they are an H beam or similar style with just the bolt they call for a stretch not a torque... TRUST ME on this one... undertorqued or not stretched properly will stretch them and spin a bearing at minimum... again, trust me.. I had 2 different guys destroy 2 engines both because of bad decisions concerning rod bolts... the last one ruined basically everything, block, pistons, cam, crank, pan... all junk... do it correct the first time!

the rods should be torqued by amount of stretch not by a specific foot pound number.

They need to be torqued to .005"-.008" of stretch.

If you don't have a way of measuring the bolt stretch, a 7/16 CARR SPS rod bolt torques to 75lbs with molly lube on the threads. This torque spec will get you within the bolt stretch spec's. If the bolt has a washer under it, which most do not, it will torque to 90lbs.
