Degreeing Cam by Measuring Overlap @ Lifters

I've had cams or timing sets...hmmm.. be 8 degrees OFF. Usually mopar cams that I used with jp performance timing sets.

I've also had more cams be dead nuts on the closing.

I set it to intake close where it should be or where I want it for the car it's going in, usually advanced 4-6.
If I spec the entire build.. I set it where the card says.. because the cam is right for what I'm doing.

If it feels soft now.. doesnt crank a ton of cyl pressure.. advance that ***** 4 degrees at least. I've put some in 10 degrees advance..lol.. enough advance to throw the tires off the wheels..
