Gonna be adjusting the valves this weekend. I have a BBC 468, solid roller cam, 12.5-1 compression. I know the motor does ''NOT'' have to be running. I'm adjusting the valves because i'm swaping correct lenght push rods over the too long ones in the motor. I did not build the motor. Steve Anderson from Patton racing engines built it.
The specs need to be at .0026 clearence. Now.....I need to make this adjustment with exhaust stroke closed??? or, open and intake closed/open?? I'm confused here. Not a motor head. Still learning. Bare with me if I've mentioned something wrong. Thanks guys.
