The only info that I could find on the truck was a picture on Pinterest. It was titled as a LV1000. If that is correct, it would have a "V" configuration engine. The 3208 although a v configuration, didn't come out until 75 I think. You would have to modify the AMT Cat slightly to make it a 3208 instead of just a straight Ford engine, but it would still be too new. I would lean toward a Detroit 8v-71, but I'm just guessing. I have several reference pictures where I built an LNT1000 a while back if you need any.
