*Remove the distributor cap and note where the rotor is pointing- on a V8 it should be close to either #1 or #6. If it isn't, the timing has jumped, providing the timing marks are correct.

In cases where the timing has been disturbed or the engine has not run yet and it's suspected the cam phasing to be wrong, the following method from Comp Cams can be used to degree the cam. This will show if there's any error in the way the cam was ground, or a problem w/the timing set:

In cases where the timing has been disturbed or the engine has not run yet and it's suspected the cam phasing to be wrong, the cam can be degreed using the "intake centerline method" (linked instructions from Comp Cams). This will show if there's any error in the way the cam was ground, or a problem with the timing set:
