What engine came in a 1983 Dodge Ram?

In brief, the 1983 Dodge Ram offered three engine options: the inline-six Slant-6 225 (3.7 L), and two V8s—the 318 cubic inch (5.2 L) and the 360 cubic inch (5.9 L).


Beyond that, the Ram’s engine options varied by trim level, drivetrain, and intended use within Dodge’s D-Series lineup for the 1983 model year. The information below outlines the main powerplants that Dodge marketed for that year and how they typically paired with other Ram features.


Engine options for the 1983 Dodge Ram


The following engines were commonly available across the 1983 Dodge Ram lineup. The list reflects the main choices customers could select when ordering a Ram pickup in that year.



  • Slant-6 inline-six, 225 cubic inches (3.7 L)

  • 318 cubic inch V8 (5.2 L)

  • 360 cubic inch V8 (5.9 L)


Most Ram configurations offered these engines with a range of transmissions and optional features, from simpler work-truck setups to higher-spec or heavy-duty configurations. The exact horsepower and torque depended on carburetion versus any fuel-injection options, as well as the chosen transmission and rear-axle ratio.


Inline-six Slant-6: 225 cu in (3.7 L)


The Slant-6 225 cubic-inch engine was a long-running staple in Dodge trucks, prized for reliability and torque at low to mid RPMs. In 1983 Ram pickups, this engine typically served as the standard or base powerplant on many trims, particularly where fuel economy and ease of maintenance were priorities. It used a carbureted setup on most configurations of that era, delivering modest horsepower but solid pulling capability for everyday trucking tasks.


318 cu in V8: 5.2 L


The 318 V8 provided a balance of power and refinement suitable for everyday driving and lighter towing duties. In 1983 Ram applications, the 318 was a common upgrade over the Slant-6 for customers needing more overt acceleration and highway performance, with variations in carburetion and exhaust that influenced output.


360 cu in V8: 5.9 L


As the largest engine offered in many 1983 Ram trucks, the 360 V8 gave the Ram the strongest towing and hauling capability of the lineup. This engine was favored by buyers who needed maximum torque and endurance for heavier workloads, though it typically came with lower fuel economy than the smaller options.


Summary


The 1983 Dodge Ram offered a straightforward engine lineup: the reliable Slant-6 inline-six at 225 cu in, and two small-block V8s—the 318 and the 360. Your choice among these depended on balance between economy, power, and intended use, with the Slant-6 serving as the workhorse baseline and the 318/360 providing progressively stronger performance for heavier-duty tasks.
