Thread: 1966 396 torque spec question

Tweet

Hello, I'm rebuilding a 396 from a 1966 Impala SS. I have the manual and the only torque specs I see for the rocker arms, is for the Rocker Arm Stud, which is 50ft lbs.

Can anyone advise on what the torque specs are for the rocker arm nut? I don't want to get it to tight or to loose.

Thanks

I never set lifters by torque. Check this page:

good info there, here is what i gathered from that

". When you feel resistance in the pushrod as it applies pressure to the socket in the rocker arm and lifter - STOP, now you will adjust the nut down "Only" 1/8-1/2 turn further. If you operate your engine a consistent high RPM, use the slightly lighter setting of (1/8 turn)."

Good info there, here is what i took away from it. Is this correct?
