Where should rotor point big block Chevy 71 some say the?

The rotor in a 1971 big-block Chevy should point to the number one spark plug wire location when the engine is at top dead center (TDC) on the compression stroke of number one cylinder. This is a critical point for proper ignition timing. There's no other "some say" about this – it's a fundamental principle of distributor and ignition system setup.
