What are the torque specs on a crank pulley bolt for a 350 sbc??? Also, what is the torque spec on the dampener bolt. I lost a crank pulley bolt and I believe the dampener bolt is loose (washer has play to it).

I bought a grade 5 bolt from a hardware store. The crank pulley bolts from an auto parts store were $9.00 as opposed to $.48 cents from a hardware store. Is a grade 5 strong enough???

Thanks!

 

I'd get a good set of grade 8 bolts if it were me. I believe the torque is 50 ft/lbs for all the crank bolts.

 

Goodentite.
