Gasser,
Those are pretty sweet but I don't think they come with a title, can not be registered and are not street legal. Plus at $90K I doubt many people will ever even see one!

I'd try to find a junkyard V8 on the cheap and slam in there. You'll spend more money trying to boost a 6 banger and might wind up with reliability problems to boot. Just my opinion. [S
