Yes.

The stock distributor can only go back on the car in one position as flatjack9 said. The stock distributor's timing is set before reinstalling on the car.

But this aftermarket Mallory distributor is different, has key-slots on the distributor's mounting base. This allows for a huge range of timing adjustment after installed on the car. So yes, should have marked a key slot before removing. And these engines do not have a timing mark on the crank pully for adjusting timing with a timing light.

So I would suggest you now go trial and error. Loosen the three mounting bolts and rotate the distributor bit-by-bit until you can get it to fire. Rotate a bit, tighten one bolt, and get your hands out of there before cranking. Caution: don't attempt to rotate while engine is cranking! Repeat until hopefully the timing gets close enough to fire: loosen, rotate a bit, tighten, hands out of there, crank.
