How much does a Chevy 250 inline 6 weight?
The Chevy 250 inline-six typically weighs about 550–600 pounds as a bare engine and roughly 600–700 pounds when fully dressed with common accessories. Exact figures vary by year, model, and how the engine is equipped.
Weight ranges for the Chevy 250 inline-six
The figures below reflect typical ranges reported for the 250 inline-six used in Chevrolet trucks and cars across generations. They provide general guidance; precise numbers come from the factory service manual or a weighed engine for the specific year and configuration.
- Dry weight (engine alone: block, heads, crank, pistons, rods, bearings, timing cover, oil pan, etc.): approximately 520–600 pounds (about 235–272 kg), depending on year and machining tolerances.
- Weight with common dress components (intake manifold, exhaust manifolds, carburetor or fuel-injection hardware, starter, alternator, water pump, and flywheel or flexplate): about 600–700 pounds (roughly 272–318 kg).
These ranges give a broad sense of the engine’s heft. For a precise figure on a particular engine, consult the factory service manual or weigh the engine as equipped in a specific vehicle or test setup.
What affects the weight and how to verify exact numbers
Several factors influence the exact weight of a Chevy 250 inline-six, and there are practical ways to verify the number for a given unit.
- Engine variant and year: The 250 inline-six evolved over decades, with small variations in casting and machining that affect weight, though the core remains cast-iron.
- Block and head materials: The 250 used an iron block and iron heads, which drive heavier weight compared with aluminum blocks.
- Installed accessories: Air conditioning, power steering, heavy-duty cooling, and other optional equipment add weight to the installed unit.
- Flywheel vs. flexplate: A manual transmission (flywheel) typically adds a bit more weight than an automatic setup (flexplate).
- Fluids when weighed: Engine oil, coolant, and other fluids can add to the “wet” weight versus a dry engine.
For an exact number, obtain the engine’s weight from the specific year/model’s service data, or weigh the engine with the engine hoist in a controlled setting to account for all attached components and fluids.
Summary
The Chevy 250 inline-six is a substantial engine, typically weighing about 550–600 pounds dry and around 600–700 pounds when fully dressed with common accessories. Variations arise from year, model, and installed options. For precision, reference the year-specific GM service data or perform an actual weigh-in with the engine fully assembled and caged for measurement.
How much horsepower does a Chevy 250 inline 6 have?
With its 3.875-inch bore and 3.53-inch stroke, the 250 offered a practical balance of performance and economy, producing between 105 and 155 horsepower depending on year and carburetor setup.
How much does a 6.0 L engine weight?
The weight of a 6.0L engine varies by model, but the Ford 6.0L Powerstroke diesel weighs approximately 920 to 966 pounds, while a Crusader 6.0 HO MPI marine engine weighs around 930 pounds. Other 6.0L engines, like the Chevy Vortec, will have different weights that can vary based on their specific build.
Ford 6.0L Powerstroke Diesel
- Approximate weight: 920–966 pounds (418–438 kg). The higher figure likely includes fluids, while the lower figure is for the dry weight.
Crusader 6.0 HO MPI Marine
- Approximate weight: 930 pounds (422 kg).
Other 6.0L engines
- Weights vary significantly depending on the manufacturer and specific application (e.g., truck, marine, performance). For example, a Chevy Vortec 6.0L engine will have a different weight than either the Powerstroke or Crusader engines.

How much does a 6 cylinder engine weigh?
A 6-cylinder engine typically weighs between 450 and 700 pounds (approximately 204 to 317 kg), but this can vary significantly based on the engine's design, materials, and accessories. For example, an aluminum V6 will be lighter than a heavy-duty cast iron inline-6, and the weight increases when you add fluids, the transmission, and other components.
Factors that influence engine weight
- Cylinder configuration: A V6 engine is generally shorter and can be lighter than an inline-6 due to its more compact design, but the overall weight depends on materials.
- Materials: Cast iron engines are heavier than those made with aluminum blocks and heads.
- Accessories: The weight increases with the addition of components like the alternator, power steering pump, and air conditioning compressor.
- Size and displacement: Larger engines with higher displacement, like a 6.0L V6, will be heavier than smaller ones, such as a 2.0L inline-6.
Examples of 6-cylinder engine weights
- V6: A modern V6 engine can weigh around 300 to 450 pounds (136 to 227 kg).
- Inline-6: A cast iron inline-6 can weigh between 400 and 650 pounds (181 to 295 kg) depending on the model.
- Specific engines:
- GM 3.6L V6: 370 pounds (168 kg)
- Ford 200 cubic inch inline-6: 380 pounds (172 kg)
- Chevy 4.3L V6: 430 pounds
