I need the order of the cylinders, if im looking from the front of the truck - for a 46 ford truck with the g-series flathead siwith the distributor mounted in the front) - is cylinder number one towards the front of the engine?

 

The books I have only go back to 1964. any I6's Ive seen have been #1 in front #6 in rear. It used to be years ago all american made 6 cyl firing order was 153624.
15 is to young to date, 36 is to old, and 24 just right.

I'm sure one of the more knowledgeable guys will be here to answer your question with more certainty
