Degreeing a cam

Say you're supposed to be installed advanced 4* and you're really installed retarded 4*. That's 8* retarded from where it should be and not too terribly uncommon.

Although not an end all be all, I generally like using the same brand timing set as the camshaft. For whatever that's worth.

Oh and that crank gear in the pic up there needs another notch or two in it.
