Duesenberg....1932 J body supercharged strait 8, 340 Hp
Hey why the hell not.
I think the thread is about replacing a Viper, i.e. "what other car would you have (if you could not have a Viper)." Not what car would you have if you could have any car in the world. That question begs a completely different mind set and is much more easily answered. Why not a Bugatti...etc.
This thread is better addressed bearing in mind the relative cost of the SRT (say $85,000).
In 1932 the Deusenberg was powered by a 420-inch straight-eight with chain-driven dual-overhead camshafts, four valves per cylinder, and a supercharger. It produced about 300 hp and drove the Duesenberg to over 120 mph, an astonishing top speed in those years.
Many Duesenbergs carried custom-built bodies, which is why you'll seldom see two alike. Among them is the one-of-a-kind 1929 Duesenberg Model J Torpedo Murphy Boattail. An aluminum-bodied convertible, it sold for $15,000 when new. The current owner is retired ASC Controls president Bill Chorkey of Farmington Hills.
As mentioned, two of the two short-wheelbase Duesenberg SSJ LaGrande Supercharged Speedsters were originally owned by Clark Gable and Gary Cooper. "Short" being a relative term in this instance as the wheelbase was longer than a Chevy Suburban.
