F100 Custom Dual-Quad 454 V8 Automatic Leather . Pop the hood and youll find 454 cubic inches of legendary Chevrolet big block that, thanks to classic dual-quad induction, turns a hefty horsepower into wide smiles! That proven powerplant has, along with the trucks cooled Turbo-Hydramatic 3-speed, been tuned for a maximum combination of performance and efficiency. The performance aspect of that equation is greatly helped by a 9-inch Ford pumpkin thats finished with a posi-traction differential and fun, 3.50 gears. Power rack-and-pinion steering makes parking easy and turns a cinch. A polished brake booster juices polished Wilwood calipers, which clamp four drilled and slotted rotors.
