A trans code off the Warranty data plate would help... it might be on the drivers door by the latch, or glove box door, i not 100% sure where it is on a 350.

The TRANS code is listed on the Warranty Plate, located on the left door face below the latch.

F = Borg Warner T-18.

N = New Process 435 - Reverse is back-towards the seat.

The only V8 available in 1965/67 F100/350's was the 352 2V.

If your truck does have a 390, it was swapped in.

On sale day, 352 engines magically become 390's.

Measuring the stroke will determine the size: 352 = 3.50" // 390 = 3.78"

I love my old truck it has a flat bed on it and is stout as an ox and as slow as one as well (top speed 45 mph). i only use it around the farm and for hauling fire wood. i found a pto online and i'm going to call about it monday , they are around 150.00 . i want to mount the winch under the flat bed so i can pull broken down tractors onto trailers and trees out of the woods i'm try to get some pics of the old girl on here. if you want to hear more about the old truck i'd be happy to talk about her some more.
