Okay granted its set up for drag racing and it certainly looks immaculate but at 3145 pounds and 9.37 e. t. that's gotta be close to indeed 425 horsepower plus about another 300.
The 425 number is what NHRA uses to determine your class. Shipping weight divided by HP “rating” puts this car in C, hence the SS/CA designation. The motors then make about 75-125% more than this rating in Super Stock.
