Some of the newer HEI systems have rev limiters and spark advance electronics built into the module itself. So you can have issues with the rev limited failing causing misfires at lower than normal rpm's or the spark advance system fails and you will still have spark but can and will be out of time.

It used to be that you would either have spark or no spark. Now you can have spark but still have a bad module. If timing was off, you would check flywheel key to see if it was sheared. Now the module can imitate a sheared flywheel key.
