Buying Guide: What to Look For in the Best 8.7L Hemi Engines
Let’s be clear from the start: the 8.7L Hemi isn’t a factory engine you’ll find in a production vehicle. It’s a beast born from the aftermarket world, typically a stroked version of the legendary 6.4L (392 cubic inch) Hemi. When you’re looking at a built 8.7L Hemi, you’re talking about a serious investment in power and performance. I’ve spent a lot of time around these engines, and the key to a good one comes down to the builder’s choices and the quality of the components used.
The foundation of any reliable 8.7L is the block itself. A used 6.4L block can be a good starting point, but for serious power, many builders prefer the stronger iron blocks from earlier Hemis or even aftermarket blocks like those from Mopar Performance. The “stroker” part of the equation is the crankshaft. A forged steel crankshaft is non-negotiable for longevity, especially if you plan on adding forced induction later. Connecting this crank to the pistons, you need H-beam or I-beam connecting rods, also forged, to handle the increased stress. For pistons, forged aluminum is the way to go for strength and to manage the higher compression ratios these engines often run.
Don’t overlook the top end. The cylinder heads are where the power is made. Stock 6.4L heads are decent, but ported and polished heads from a reputable shop will make a dramatic difference in airflow and power. Pair them with a camshaft that matches your intended use—a lumpy, aggressive cam is fun but might be a pain for a daily driver. Fueling is another critical area. The factory fuel system won’t cut it. You need high-flow fuel pumps, injectors, and a tune specifically calibrated for the increased displacement and airflow. A bad tune is the fastest way to turn your expensive engine into a paperweight.
When considering a Best 8.7L Hemi Engines Review: Power and Longevity, the real takeaway is that longevity is a direct result of quality parts and expert assembly. Power is easy to make; making it last is the hard part. Look for builders who are transparent about their component choices and who have a proven track record. Ask about the machine work, the clearances they use, and the dyno testing process. A well-built 8.7L Hemi is an absolute monster that can be both incredibly powerful and surprisingly dependable, but it all hinges on the details from the very beginning.
Frequently Asked Questions
How much horsepower can I expect from a built 8.7L Hemi?
This is the first question everyone asks, and the answer depends entirely on the build. A naturally aspirated (no supercharger or turbo) street build with good heads, a cam, and intake can reliably produce between 550 and 650 horsepower at the crank. If you add a centrifugal supercharger or a twin-turbo setup, you’re looking at 800 to over 1,000 horsepower without breaking a sweat. The beauty of starting with such a large, strong foundation is that it responds exceptionally well to boost.
Is an 8.7L Hemi reliable for a daily driver?
It can be, but you have to be honest about your definition of “daily driver.” A well-built 8.7L with a mild cam, good tuning, and all supporting mods (like a beefier cooling system) can be driven regularly. However, expect lower fuel economy, more engine noise, and potential drivability quirks compared to a stock engine. It’s a high-performance piece, so it will always demand more attention and a thicker wallet at the gas pump than a factory engine.
What is the cost of building or buying a complete 8.7L Hemi engine?
This isn’t a cheap endeavor. A quality long-block assembly (block, crankshaft, pistons, rods, and heads) from a reputable builder can easily start between $12,000 and $18,000. That’s before you add the cost of intake manifolds, throttle body, fuel system, ignition, headers, and the essential custom tuning. A full turn-key setup, ready to drop in and make power, often lands in the $20,000 to $30,000 range. You are paying for specialized labor and high-end components.
What vehicle is best suited for swapping in an 8.7L Hemi?
Classic Mopar muscle cars like the Charger, Challenger, and Cuda are popular choices because they have the space and the “soul” for such a motor. Modern Dodge Challengers and Chargers already equipped with a Hemi are also excellent candidates, as many components can be carried over, simplifying the swap. Trucks like the Ram 1500/2500 can also handle it, but you need to consider transmission and driveline strength. The key is to match the engine to a chassis and drivetrain that can handle the immense torque.
What kind of fuel system upgrades are necessary?
The factory fuel system will be completely overwhelmed. You will need a return-style fuel system with a high-pressure in-tank pump or multiple pumps, along with a boost-referenced fuel pressure regulator. Fuel injectors need to be sized for your power goals; think 1000cc to 1500cc injectors for forced induction builds. This is not an area to cheap out on, as improper fueling is a guaranteed way to experience a very short and expensive life for your engine. When I look at any Best 8.7L Hemi Engines Review: Power and Longevity, the fuel system is always a major point of discussion for a reason.
