The biggest one that fits!
Kit available at auto parts w/instructions
I'll have to watch the movie again, but online pictures I've seen of it make me believe it is basically a 1972 Buick Riviera that has been customized. The front fenders appear to be from a '72 Buick Riviera, the grill looks '72 Riviera, basic shape of the front end looks '72 Riviera.A view of the rear half of the car would be most telling. Not being able to find a full side shot online, this is a best guess, but it is definitely early '70's General Motors, likely in the Buick bloodline.
E-body same as Eldorodo and Toronado which are front wheel drive, while the riv rear wheel.
I think a hotter cam , aluminum heads and intake probably headers maybe that tougher block I've heard about . Its a much faster car .
