I would suspect anything that is 6V compatible would use 3.3V for power and logic if the designers had any sense (and parts availability) but who knows.

A 6V car in good condition will drop to about 5V when cranking so I would hope the ignition could use 5V no problem.

One thing to try is to hook the ignition straight to the battery terminals to test. You will bypass any voltage drop. Ironically, for cars with undersized battery cables, the battery terminal voltage will actually be slightly higher than if the cables were correct, when cranking.
