Cost Breakdown
Engine Block
The engine block is the foundation of the build. A new 6.4 HEMI engine block typically costs between $2,500 and $3,500, depending on the supplier and any additional features.
Forged Pistons
Forged pistons are essential for high-performance applications. They can withstand higher temperatures and pressures. The cost for a set of forged pistons ranges from $600 to $1,200.
Custom Crankshaft
A custom crankshaft is crucial for optimizing engine performance. Expect to pay between $1,500 and $2,500 for a high-quality crankshaft.
Connecting Rods
High-performance connecting rods are necessary for handling the increased stress of a built engine. They usually cost between $600 and $1,000.
Camshaft
The camshaft controls the timing of the engine’s valves. A performance camshaft can range from $300 to $800.
Cylinder Heads
Upgraded cylinder heads improve airflow and performance. A set of high-performance cylinder heads can cost between $1,200 and $2,000.
Intake and Exhaust Manifolds
The intake and exhaust manifolds are essential for engine efficiency. Expect to spend around $500 to $1,500 for both.
Oil Pan and Accessories
The oil pan and necessary accessories such as gaskets, seals, and fasteners can add another $300 to $600 to your budget.
Fuel Injectors and Ignition System
High-performance fuel injectors and an upgraded ignition system are crucial for optimal performance. This can cost between $400 and $800.
Cooling System Components
Ensuring your engine stays cool is vital. Cooling system components can range from $200 to $500.
Total Estimated Cost
When you sum up all the components, the total estimated cost for building a 6.4 HEMI with forged pistons and a custom long block can range from $8,000 to $15,000, depending on the choices made for each component.
Conclusion
Building a 6.4 HEMI engine with forged pistons and a custom long block is a significant investment but can result in a powerful and reliable engine. Understanding the cost breakdown helps enthusiasts plan their builds effectively and make informed decisions on components.
