I need to know what the torque specs are for rod bolts on a 455 from a 70 Riv going into my 69 GS. according to #'s, my buick recuild book didn't have them. It was either 65 or 75, so I went with 70 and the torque wrench wouldn't set. End result, I snapped one and stripped the other on the same rod. Rod specs, head specs, balancer specs, headers if there are.... :beer Thanks, Scott
All I have are '72 455 specs from a Buick factory service manual: These are all in ft/lbs: Rods 45, mains 110, heads 100, balancer 200 min., Intake manifold 65, Rocker shaft 25, ex. manifold 18, but headers may be different. I tried to copy it for you and send it but it's not working. Hope this helps!:Smarty:
