    Thank you for responding! I couldnt wait any longer so I found the torque spec for the 20r which is 45 ft lbs so thats what I used.

    I got it back into my car and running but something still isn't right. My motor is noisy as hell. It could be the tranny too but IDK. I think i might have to just replace them both. This is getting rediculous. I wish I could find the problem and just fix it. I am going to check the cam bearings and the valve adjustments next.

    Any ideas?
