Dodge Dakota Engine Swap Considerations
When planning an engine swap for a Dodge Dakota, several factors need to be considered beyond just bolt patterns. Here’s what to keep in mind:
1. Transmission Compatibility
Not all engines pair with all transmissions. For example, the 4.7L V8 is commonly paired with a 46RE automatic transmission. Manual transmission swaps often require custom bell housings or flywheel changes.
2. Engine Mounts and Chassis
Some swaps, particularly those moving from V6 to V8, may require custom motor mounts. Older first-generation Dakotas may need reinforced crossmembers to accommodate larger engines like the 5.7L HEMI.
3. Wiring and ECU
Modern Dakotas (2000 and newer) are equipped with complex electronic control systems. Swapping engines often requires the donor ECU, full wiring harness, or ECU tuning to ensure proper operation.
4. Exhaust and Intake
Different engines may require modifications to the exhaust system, headers, or intake manifold. For instance, moving from a 3.9L V6 to a 4.7L V8 requires wider exhaust and sometimes relocation of catalytic converters.
5. Fuel System
Larger engines, such as V8 HEMIs, demand higher fuel flow. Upgrading the fuel pump and injectors may be necessary when performing high-performance swaps.
6. Cooling System
Ensure the radiator and cooling system are compatible. V8 engines often produce more heat, which may require a larger or upgraded radiator.
7. Legal and Emission Compliance
Certain swaps, especially those crossing model years, may require compliance with emissions regulations depending on your location. Check local laws before completing the swap.

Popular Dodge Dakota Engine Swaps
1. 4.7L V8 Swap
The 4.7L V8 is one of the most popular swaps for Dakotas with the 3.9L V6. This swap increases horsepower significantly (up to 235 hp stock) and is compatible with most 1997–2004 Dakota transmissions. Minor wiring and ECU adjustments are usually necessary.
2. 5.7L HEMI V8 Swap
For high-performance enthusiasts, the 5.7L HEMI V8 offers massive power gains. While the bolt pattern is compatible, this swap is more complex and requires upgrading the transmission, fuel system, and ECU.
3. 3.7L V6 Upgrade
For Dakotas that originally had a 3.9L or 3.3L engine, the 3.7L V6 is a modern replacement option. It’s more fuel-efficient and easier to integrate into 2005–2011 Dakotas.
4. Diesel Engine Swaps
While rare, some Dakota owners have attempted swaps to small diesel engines. These are more complex due to transmission, fuel system, and cooling requirements, and often require custom fabrication.
