Merc BB rod bolts

Hi, I´m rebuilding my BB, but I cant find torque spec for rod bolts, 7/16. There is stamped SPS and a little "C" on the bolts. Any one how can help me.

The engine is in .060 od and using TRW 2399 pistons, weiand x-lerator intake, B&G 750 carb, Stelling headers, rect heads, and some other stuff. This engine is going to run in CC Scorpion 230. Trying to use Alpha drive, but ... I know bravo should be better

If Its A Replacement Rod Bolt For A Dimple Rod It Should Torque To 70-75 Ft Lbs. IF THE BOLTS ARE USED CHECK THEM FOR STRETCH AND MAKE SURE THEY STRETCH EVENLY.
