Ron,
I did some searching on the web to try and identify your engine based on the provided "F1016PF" info.
Can't find any listings for any Chevy I6 engines (216, 235 or the later style 194, 230, 250 and 292) that listed "PF" as an engine identifying "suffix" code.
We need more information to try and determine what this particular engine is. Please provide pictures of:
Overall view of left and right sides of this "235" in question.
Stamped engine serial number.
Engine block "casting number" (should be on the passenger side of block lower down near the oil pan mounting surface between front of engine and starter).
Engine block "casting date" (should be on lower passenger side of block near engine serial number stamping pad).
Once we have these pictures, it will help us help you in knowing exactly what engine you have before further conversation on mating this up (possibly) to your '41 AK.
Looking forward to seeing what you can provide.

Dan
