| Re: torque specification on 1989 firebird 305. there is no torque spec, and for good reason. The correct procedure is to make sure the one your adjusting is on the base circle of the cam, not at all on either ramp of the lobe, then spin the pishrod between a thumb and finger while tightening the rocker nut with your other hand. I'm right handed, so my right hand holds the ratchet/socket. Slowly tighten the nut until the pushrod becomes difficult to spin, then turn the nut at least another 90 degrees. Try that, then if you have trouble, report back. |
