6. Shelby S.P. 360
Plenty of people know all about Shelby’s muscle car exploits, because they’ve become legendary. Although, one car has slipped through the cracks and out of the awareness of many enthusiasts: the S.P. 360. While this vehicle wasn’t from the heyday of American muscle, it’s worth including.
Shelby took a Dodge Durango, kept the stock engine, and threw in a Kenne Bell 2,200 Blowzilla, which provided 13 psi of boost. Not stopping there, Shelby also applied a Ram Air induction kit, Kenne Bell Extractor dual exhaust headers that were equal in length, and an Optimizer ECU. All that pushed the V-8 to 360 horsepower, instead of the stock 250 horses.
7. Stutz Blackhawk
The final obscure American muscle car is a rare gem from Stutz, a nameplate that was resurrected in 1969. Many were shocked when they actually drove the car, because the Blackhawk looked regal and nothing like muscle cars of the time. Among the unique exterior features were side exhaust pipes, freestanding headlights, a spare tire embedded in the trunk lid and a swooping beltline.
Despite its more luxurious feel, at the heart of the vehicle was a Pontiac 455 V-8, giving the Blackhawk a real wicked streak. It pushed out 320 horsepower and 420 lb.-ft. of torque, which made for some explosive acceleration.
If you’re lucky enough to see a Stutz Blackhawk today, they’re quite the thing of beauty and raw power.
