Ask some of your fellow club memebers. Dont know if they are out there/if it is really true. You never know.Which ever way you decide, best of luck. Sounds like it will be a sweet ride.
Your father is correct. However, to my knowledge, there were very few factory builds that involved the mating of a 335 series engine to a C4. So few in fact that it is next to impossible to find a bellhousing if you want to use a C4. Generally, the 289, 302, 351C, 351W have the same bellhousing bolt pattern and can mate a C4 or a C6 to it. Now, the 351M, 400, 429, 460 have the same bellhousing bolt pattern and are primarily C6 trannies only, these are not the same bellhousing bolt patterns as the 289, 302, 351C, 351W engines. In fact, ford has around three different C6 bellhousing patterns, and none are interchangeable, ie, a 400 C6 won't bolt to a 302.... same with the torque convertors.

Now, there might be some places out there that make adapter plates that you could mate a C4 to a 335-385 series engine. I've just never wanted too, I'd much rather stick with a C6. They suck up a little more energy, but dang they can take most anything you throw at 'em. I've heard mixed reviews about the C4, however. As in being able to take the same amount of power that a C6 could take. Drag racers like them because of the weight savings, some hate 'em because they don't last. To me, your engine build recipe will dictate what tranny to go with. If you have a trusted tranny guy that can really build up a C4 to take whatever you throw at it and you trust your builder, then you probably can't go wrong. I had my C6 built up to take whatever I throw at it. I don't expect any problems.

Here's a sort of guide to what you may or may not be able to mate up to whatever engine tranny combo you're thinking of.
