Dave,
"Special Kind of Crazy" refers to be the kind of person that wants a Nasty Boy. You really have to love Healeys and be convinced for whatever reason that it's better than whatever you can buy for the same amount of money. I wanted one for years and am glad I finally went ahead and did the V8 swap. In my view, it has all the Healey virtues with an extra one of much-improved performance. But I already had a Healey that I had bought about 30 years ago, with a great frame and a body that I had completely refinished. It was like doing a swap in 1967 on a 1963 car. But as you found out, it now costs a lot of money just to find a Healey to use as the basis for a swap and you are probably going to have to do some degree of restoration before you do the swap. I bet you couldn't buy the one on auction and get it into good running shape without being in the neighborhood of at least $40k after you've rebuilt the engine, tranny and everything else it needs and that's if you wanted to leave it as a "rat healey" and clear coat the body. Compare that to a Factory Five, which you have to admit has a much better chassis, brakes and suspension than any Nasty Boy that hasn't had a tube frame stuck under it is likely to have. And for around $25-30k for a decent used one, it's going to be way cheaper than a Healey Nasty Boy. That's why you have to be a real Healey nut to want a Nasty Boy. I don't plan on selling mine (probably ever) so ultimate resale value isn't a big concern of mine. Will a modified Healey be worth more than a kit car? I really don't know.
