I had the same thought. You would think finding a tooth count on te SBF cam
gear would be easy on the internet..., but all I could find was a reference
to 8 degrees per tooth (which equates to 45 teeth). Still if he is resetting

the timing, having the problem reoccur and resetting the timing again that
would be 16 degrees at the cam - if teeth are slipping. At that point I
don't think he would get it to 'run well again' like he has. It sure sounds
like the distributor gear is spinning on the shaft. Given the load of cold
oil at the pump spinning off the distributor it would give reason to it
setting correctly and then shifting again on start up - later when cold. Tom
