I don't think the registration would do it, but if it were a title then it would get down to terminology. If the title just said 1927 Ford, or Ford roadster, coupe, tudor, whatever, then it would be transferred using the same nomenclature. No inspection, no emissions testing, just pay the registration fee, filing fee, agent fee, and "excise" tax (same rate as sales tax, even though the purchase is from out of state ) based on the bill of sale, or if they don't like that number (in other words they think you faked it low) they have a data base of "suggested" values that they'll use. If the registration says "homebuilt" that might cause some extra effort. I've not dealt with that particular situation, nor have I had any friends with that experience. Given the way this state thinks, you might end up having to have an inspection and state assigned vin, along with some proof of what year it was assembled. It would probably be handled similar to a "kit car". Likewise, if you only had a registration and bill of sale, you'd have to post a lost title bond and wait the 5 year "protest" period before you get a clear title. Otherwise, if there were only a registration, it would be cleaner to file for a lost title replacement from the registered state, and try to get their title first. Personally it's too much hassle for me with anything but a clean title, and few cars are rare enough to warrant that much stress.
