Wanting to get into American muscle
Yeah, BB. There's one for sale in Long Island, NY that is done to the MAX in Plum Crazy like my Duster was. Looks like a drag car, but is a pro-street setup. See link & pics below.
The 440 Dusters I've seen make my heart skip a couple of beats (I have A-Fib anyway). A lot of them have been reinforced to keep the unibody from pretzling. Those are drag cars.
Guys are boring and stroking their 340's to 416's (or something like that) and getting big HP numbers. The BB's weigh 100#+ more, but aluminum heads bring that number down.
