Re: Finally some Cam Degree Numbers - Now what?

Just some numbers to ponder: His readings show the exhaust closing at 9 ATDC - with .014 lash. The cam card specifies 19 degrees ATDC - with zero lash. So you can assume that with zero lash, it...

Re: Finally some Cam Degree Numbers - Now what?

While one cam-gear tooth is approximately 8 degrees of cam timing, the crank turns at twice the speed, so it is 16 on the crank.

360 / 44 = 8.18 (cam gear has 44 teeth)
360 / 22 = 16.36 ...

Re: Finally some Cam Degree Numbers - Now what?

Or, if you have "adjustables", just back out the adjuster until you feel it tight against the valve (when the lifter is on the heel of the cam). Even if you go a bit too far, you've taken up the...

Re: Finally some Cam Degree Numbers - Now what?

You should do it with zero lash - and use the .050 numbers (they tend to be more accurate). We have no idea as to how the opening ramps influence the timing - only way to figure it out is with the...
