$ Building a Slant 6 for performance

Sounds a lot like V8 mods? Yes, what I was saying is that after spending all of that money on a slant, it still carries not much residual value, other than selling off some bolt-ons.
Building up a smallblock, it is still worth something and a heck of a lot easier to sell(in the car or not) if need be. If a /6 build is what you want to do,that's just fine, but if you change your mind and want small block after all, be prepared to take a bigger hit $$$ wise.

That's all true, I think.

But, I've never built a car with the idea of selling it. I can't think that far ahead!!!

That's probably why I've never had any money...

Oh well...
