Putting a cam back to zero, how much does it move?

I have a ford 302. The cam was moved to 6 degrees advanced on the crank gear. I'm moving it back to zero, with a new chain too. I put the new gears and chain on, and i'm not sure the cam moved at all. How much of a turn, at the cam, is 6 degrees? The pin took a little persuasion to go into the cam, would that have been it trying to move the cam 6 degrees back to zero?

Just wanting to double check myself before I button this thing up. Been a long time since i've done this stuff. Thanks!

 

Six degrees is not very far like probably a tooth

Yeah, the cam would only be moving 3 degrees. That's like one half of one minute on a clock.

 

That's what I was hoping. I was thinking the resistence I had putting on the chain, was the cam repositioning itself. Hoping this solves my hard starting and total advance issues.

 

New chain? Typical new chain can stretch 2-3 degrees untill it settles down. Dialing in @ 0 will probably result in it being slightly retarded. A lot of the aftermarket cams do have some advance built in also, might check on that too.

 

Why would that have an effect on either?

 

oops - Cam timing has nothing to do with effecting your ignition timing.

Hard start and total timing is 100% in the distributor.

 

Just for reference: 1 minute one a clock is 6 degrees, so cam movement would be 1/2 a minute on the clock.

 

What's happening is the intake CL of the cam is being moved in relation to the piston's location. The pistons location is defined in degrees, not the cam's and in all cases as it related to top dead center.

We all know there's 360 degrees in a circle. & we all know the crack moves 720 degrees to every 360 degrees of cam revolution.
Exactly 2x the amount and .....

Awe hell forget it ...
