I just bought a 1968 F100. The VIN is F10YR****** which when I decoded it says it originally had a 360 (if I got it right). But the guy I brought it from said it has a 390. I got C6AE-XXXX-G off the top of the engine. Which I was told means its a '66 engine. So I'm assuming it's a totally different engine. How do I tell what engine it is?
66 parts were placed on many vehicles after 66... You will need to check the stroke of the motor (or pull the cast number off the crank), search for the how-to. This will give you a better understanding of the internals of the motor, which is where the difference between 360 and 390 reside.
