Dodge Viper V10 Engine for Sale | OEM 8.0L 8.3L 8.4L OHV Powerplant

Description

Engine Background

The Dodge Viper V10 is the 8.0L, 8.3L, and later 8.4L pushrod V10 that powered every Dodge Viper from 1992 through 2017 across five generations, plus the Ram SRT-10 pickup from 2004 through 2006. Designed by Lamborghini engineers (Chrysler owned Lamborghini at the time), built by Mopar for the original Viper RT/10, and refined across twenty-five years of production, the V10 architecture is unique in the modern era. It is the only production V10 ever offered in an American sports car, the only mass-production V10 ever offered in an American truck, and one of the largest-displacement naturally aspirated production engines ever built in the United States.

The architecture is straightforward OHV, two valves per cylinder, a single in-block camshaft driving hydraulic roller lifters and pushrods, sequential multi-port fuel injection, and a distinctive 90-degree V10 firing order. Generation 1 (1992 to 1995) produced 400 horsepower and 450 lb-ft from the 8.0L. Generation 2 (1996 to 2002) refined the 8.0L to 450 horsepower in the GTS. Generation 3 (2003 to 2006) introduced the 8.3L SRT-10 producing 500 horsepower. Generation 4 (2008 to 2010) lifted the 8.3L to 600 horsepower in the ACR. Generation 5 (2013 to 2017) introduced the 8.4L producing 640 to 645 horsepower in the SRT and ACR.

The Viper V10 has a strong following beyond Viper owners. The Ram SRT-10 pickup uses a slightly detuned 8.3L. Swap builders drop Viper V10s into Mustangs, Camaros, Ram trucks, and custom builds for unmatched torque, an unmistakable sound, and the relative simplicity of an OHV V10 compared to a modern DOHC engine.

When Replacement Becomes Necessary

• Cylinder misfire, common with cracked exhaust manifolds and ignition coil failures
• Knock or rod knock under load, indicating bottom-end bearing wear on high-mileage units
• Loss of compression on one or more cylinders, scored walls or piston ring failure
• Excessive oil consumption beyond one quart per 1,500 miles, valve seal or ring wear
• Coolant in oil or white exhaust smoke, head gasket failure (more common on Gen 1/2)
• Cracked exhaust manifold, the well-known Viper issue
• Cam sensor failure causing intermittent no-start
• Spun bearing from oil starvation, common on track-day-abused units

What to Know Before You Buy

• Generation and displacement matter: Gen 1/2 = 8.0L. Gen 3/4 = 8.3L. Gen 5 = 8.4L. The displacements are not interchangeable without significant supporting work. Generation is confirmed on every order.
• Cracked exhaust manifolds are a Viper signature issue across all generations, especially Gen 1/2. The factory cast-iron manifolds crack from heat cycling. Aftermarket stainless headers (American Racing, Belanger) are the standard fix. Manifold condition is inspected on every Viper V10 we ship.
• Gen 1 versus Gen 2 8.0L: both are 8.0L, but Gen 2 has revised cylinder heads with better airflow and higher specific output. The Gen 2 GTS produces 450 hp versus the Gen 1 RT/10’s 400 hp.
• SRT-10 truck versus Viper SRT-10 car: the Ram SRT-10 (2004 to 2006) uses a slightly detuned 8.3L (500 hp truck versus 510 hp car). Truck and car versions share architecture but tuning and accessories differ.
• ACR is track-focused: the Gen 4 ACR (2008 to 2010) and Gen 5 ACR (2015 to 2017) carry higher output, lighter components, and (on some Gen 5) optional dry sump. ACR engines command premium pricing.
• Lamborghini connection: the original V10 architecture was developed with Lamborghini input but the engine is fundamentally a Chrysler design and is built in Detroit, not Italy.
• No factory crate currently available: FCA / Stellantis discontinued Viper V10 production. Used OEM units are the primary supply path.

What Ships and What Does Not

Direct-Fit Vehicle Applications

The Dodge Viper V10 was factory installed in the following vehicles:

For swap applications, the Viper V10 has been installed in Mustangs, Camaros, Ram trucks, and custom RWD builds. The OHV architecture makes the engine simpler to swap than a modern DOHC equivalent, but the physical size and the cooling demands still require substantial chassis work. Call us with your specific project.

Used OEM Versus Specialist Rebuild

For a Viper RT/10, GTS, SRT-10, ACR, or Ram SRT-10 with engine failure, used OEM is the most accessible path. New replacement engines were never widely available outside of Mopar warranty service and are not practically obtainable today since FCA discontinued Viper production. A specialist V10 rebuild typically runs $18,000 to $30,000-plus from Viper specialists, depending on generation and target output. A documented used OEM unit, generation-verified and exhaust manifold condition disclosed, is the realistic option for most owners.

Inspection Workflow

• Compression test logged across all 10 cylinders with uniformity reported
• Generation and displacement confirmed: 8.0L (Gen 1/2), 8.3L (Gen 3/4), or 8.4L (Gen 5)
• Exhaust manifold condition assessed for cracking, the Viper signature issue
• Head gasket surface checked for active seepage
• External oil leak survey including front and rear seals, valve covers, oil pan
• Cam sensor and accessory drive area inspected
• Mileage documented where available from donor vehicle records

Pre-Purchase Buyer Notes

• Plan for exhaust manifold replacement: factory cast-iron Viper manifolds crack across all generations. Budget aftermarket stainless headers (American Racing, Belanger) as part of the install. Doing this preemptively is significantly cheaper than addressing it as a roadside repair later.
• Generation match is non-negotiable: Gen 1/2 is 8.0L, Gen 3/4 is 8.3L, Gen 5 is 8.4L. These displacements do not interchange without substantial supporting work. Confirm your chassis target before ordering.
• Cooling system service at install: the V10 is unforgiving of cooling system neglect. Replace the radiator cap, inspect the radiator, replace coolant hoses, and verify the thermostat at installation.
• Engine harness and ECU: the Viper V10 ECU is application-specific. Source ECU and harness separately if your project is a swap rather than a Viper repair.
• Specialist installation is recommended: while the OHV architecture is simpler than a modern DOHC engine, the V10’s physical size and cooling demands require experienced installation work. Use a Mopar specialist where possible.
