Can the number plug wire be put in any position on a distributor if it is set at top dead center on new motor?

Can the number (1)? plug wire be put in any position on a distributor if it is set at top dead center on new motor. Many will say no, BUT early model it was possible. If you are setting up an old points, early HEI or electronic (fomoco mopar) CARBURATED it can be done. IF you are working on a TFI or MPI NO. The spark AND injectors have to be in sync, they MUST be set up to manufacturers specs.
