Degreeing a +4 cam?
If a cam is ground +4 degrees what should it look like when you degree it? Should I get it so it winds up +4 degrees or 0 degrees. I'm so confused about this, will the spec. card take the +4 degrees into consideration or should everything wind up looking like +4 degrees.

Maybe I'm just lucky. But, I've installed several cams, and always install them straight-up. I've never degreed a cam, and never had a camshaft related problem.
The 4* advance will give you a little more low end power.

So it's my decision if I wan't the cam straight up I add 4 degrees from the specified lobe center. 112 lobe center specified, changing it to 116 would negate the ground in advance right?
Comp Cams says they grind in 4 degrees for best street performance but I wonder if they really are trying to make up for eventual slop in the chain or a sloppy chain to begin with?
This is so confusing, I suppose if it's reading 112 center it should be fine.

take the ILCA (intake lobe center angle) + ELCA (exhaust lobe center angle) and divide the result by 2. The result should be the degree angle at which to install the cam.
for example:
ILCA = 108*
ELCA = 116*
108 + 116 = 124/2 = 112* degree the cam to.
Lingenfelter Performance told me this about a year ago.
for example:
ILCA = 108*
ELCA = 116*
108 + 116 = 124/2 = 112* degree the cam to.
