On my last teardown I happened to see some movement of my main caps on my dart block. Its a 622 bbc with a dart splayed steel cap block.My question is when the caps start "walking" like this does it usually mean that there is too much timing in the motor? This motor is alcohol injected and the plug colors look good. But last year with the same tuneup I had cap walk and a main bearing spin. I am just wondering if it's timing related?
