I will be recieving my LE AFR heads, and my Bauer cam soon, and wanted to double check the degreeing of the camshaft, to make sure everything is acurate. The heads are off the engine. Can anyone please be kind enough to explain to me how this is done. I already have the degree wheel, and the dial indicator. Thank You for your time.

There is a good explanation in the Comp Cams catalog which you can view on-line at www.compcams.com

You must use the dedicated piston stop for when the heads are off. Turn the engine both ways to acuretly determine TDC. Here is the link from comp:

Hmmm. Must? I haven't EVER used a dedicated piston stop when degreeing in a cam. I'm an indicator kinda guy. If you got that from the CC site, there are also other statements made on that site I question.Originally Posted by sssalah

No sir, got that from comps’ instruction when I had to degree a friends cam years ago. I understand it’s possible to do it with a dial indicator, but it’s simpler and more accurate for a first timer and for myself (I’ve only done about 8) to use a stopper.Originally Posted by arnie

There's lots of ways to degree a cam. There is probably no single "best" way. In my own field, there are many procedures that may be performed using a number of different techniques. People tend to do any task like that best (fewest errors and complications, more quickly) when they follow the method they are personally most familiar with rather than the "best" technique.
So, whatever way works best for you is the best way.

Just noting the above statement is false. You don't have to "must use" anything. In regards to technique, there are those that will question the utmost accuracy of any method that requires the crank to be turned in both directions. There is also the possibility of applying more force than necessary to the piston against a stop. I'm not stating it is not an adequate method. When used with care, it can be acceptably accurate. I agree with Rich. Important to use whatever method you are more comfortable with.

...and, of course, if Arnie is not comfortable with something, he will let you know... Originally Posted by arnie

j/k, bud

I checked the cam degree as follows.
1. Set #1 piston TDC, with the dial indicator.
2. Set pointer to TDC on degree wheel.
3. Turn motor counter clockwise to max lift.
4. Set dial indicator to ZERO. Turn motor counter clockwise .70 to .80, then clockwise to .50, and write down number.
5. Then turned motor clockwise to zero (MAX LIFT) and clockwise to .50 and took that number.
6. Add both numbers and divided by two to get the ICL.
Correct?
