Those numbers don't mean much to me but the color under the crud along with the configuration shown in the 3rd picture says '52-'52 truck. The metal tubes in the upper coolant hoses are definetly truck. The color is '52-'53 truck. I can't see the front motor mount but if it has asinglr front mount straddling the crank and mounts on each side of the bell housing, it's '53 truck for sure.
Passenger side of intake on top of block towards the rear, should be a stamped set of characters. Those will tell you the date.
'53 Ford passenger cars had the narrow v-belts. I would be inclined to say 'truck' because of that. Not much differnece otherwise.
Truck if the collection is original would likely have hard valve seats. '52-3 passenger generally had valves seating right on the iron. Only meaningful casting number wil be prefix on the 6050/6049 numbers on heads, and of couse that only ID's the head itself... many flatheads turn out to be mixed bags of parts from exchange rebuilds. Only what's inside matters. The desireable features are no cracks, Henry styl valve seats, and Merc cranks, which can turn up anywhere after all these years.
Enlarging the pic shows it has 8RT heads and '53 truck/car waterpumps..... probably came from a '53 truck but who knows! Fan looks strange for a truck. Could be a mongrel of ass't parts.
I agree with above (maybe a mongrel) but 8RT on those heads says Truck in Ford-ese. Usually (not always), "T" in the prefix of a Ford part # indicates it was originally designed for trucks. But there are exceptions.
