I'd buy it for two reasons. I'd be able to find out where the douche who had the balls enough to mess up a prefectly good Galaxie 500 and I'd prolly make a fortune selling the parts from the floor pans down on Ebay!!
As per the car with the blower, Don't Laugh.
That blower has prolly got at least 3L of "displacement". A Cobra modular motor with a 2.3L Kenne Bell blower can hit a solid 600 or better to the wheels. That big ass motor and that BIG ass blower prolly throw that thing into the 8's or 9's.
Normally, I would venture to say something like that isn't street legal, but it seems to have the proper stickers. I know (at least in Jersey) a cowl induction hood cannot have more that a 3 inch lift or it is considered an obstruction of view. The only way around that is a set of QQ's (classic plates), but even than the cops can hassle you.
