Design a gas-powered V8 built for strenuous duty, hauling heavy loads day in and day out, built to idle for long periods of time, and give it impressive durability performance and power. The result is the overhead-valve port fuel-injected available 7.3L. This big block “pushrod” V8 with variable cam timing reaches peak power with optimal air-fuel ratio in the low rpm range, providing the responsiveness and power commercial applications require. And for the durability also required, the 7.3L features a cast-iron block with four bolt and cross bolted main bearings plus a forged steel crankshaft. Want the biggest gas V8 with the highest torque output, rated at 350 hp and 468 lb-ft. of torque, available in a chassis cab? This is it.

The available 6.7L Power Stroke® V8 Turbo Diesel features a unique inverse-flow configuration (inboard-mounted exhaust manifolds and turbocharger). This third-generation PowerStroke® has a 36,000-psi fuel-injection system featuring injectors that can measure and spray fuel up to eight times per stroke to optimize combustion and quiet the engine. To handle the increased pressure and power, the third-generation PowerStroke® features a stronger block, cylinder heads, connector rods and bearings, plus steel pistons. The results? An incredible 330 hp and 825 lb-ft. of torque.

The 6.2L flex-fuel gas V8 is the standard engine in Super Duty® Chassis Cab F-350 models. It’s engineered to deliver peak torque at lower rpm and generates high torque throughout the midrange of the power band. The 6.2L’s SOHC valve train with roller-rocker shafts results in a stiff valve train with an optimized intake and exhaust port layout for better breathing. The F-350 Super Duty® Chassis Cab also features the Ford TorqShift® 10-speed automatic transmission. What’s more, the 6.2L F-350 is available with optional Live-Drive Power Takeoff (PTO) Provision with Mobile Mode..
