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

About This Engine

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) and built by Mopar for the original Viper RT/10, 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 built in the United States.

The architecture is OHV with two valves per cylinder, a single in block camshaft driving hydraulic roller lifters and pushrods, sequential multi port fuel injection, and a unique 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) increased 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 just Viper owners. The Ram SRT-10 pickup uses a slightly detuned 8.3L. Swap builders use Viper V10s in Mustangs, Camaros, Ram trucks, and custom builds because of the unmatched torque, the unmistakable sound, and the relative simplicity of an OHV V10 compared to a modern DOHC engine.

Signs You Need a Replacement Engine

• Cylinder misfire, common with cracked exhaust manifolds and ignition coil failures
• Knock or rod knock under load, 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 1 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 (very common, well known Viper issue)
• Cam sensor failure causing intermittent no start
• Spun bearing from oil starvation, common on track day abuse units

Known Things 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. We confirm generation 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. Inspect manifold condition on any Viper V10 you buy.
• Gen 1 vs Gen 2 8.0L: Both are 8.0L but Gen 2 has revised cylinder heads with better airflow and a higher specific output. Gen 2 GTS produces 450 hp vs Gen 1 RT/10 at 400 hp.
• SRT-10 truck vs Viper SRT-10 car: The Ram SRT-10 (2004 to 2006) uses a slightly detuned 8.3L (500 hp truck vs 510 hp car). Truck and car versions share architecture but tuning and accessories differ.
• ACR is track focused: Gen 4 ACR (2008 to 2010) and Gen 5 ACR (2015 to 2017) have 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 has discontinued Viper V10 production. Used OEM units are the primary supply path.

Vehicle Compatibility, Direct Fit

Direct factory applications:

Transmission compatibility (factory): Tremec T-56 6-speed manual (Gen 1 to 4 cars). Tremec TR-6060 6-speed manual (Gen 5 cars). Ram SRT-10 used a Tremec T-56. The Viper V10 was never offered with an automatic transmission.

Used OEM vs Rebuilt vs Built Viper V10

A documented used OEM Viper V10 with verified compression, generation, and exhaust manifold status is the primary path for Viper restoration projects, Ram SRT-10 truck owners, and swap builders. Pricing is roughly half to one fifth of rebuilt or new options. Our Viper V10s are compression tested across all 10 cylinders, generation confirmed, and exhaust manifold condition disclosed.

A professionally rebuilt Viper V10 from Arrington Performance, Roush, or Mopar specialty rebuilders typically runs $15,000 to $25,000 depending on generation and rebuild specification. Standard rebuild includes new bearings, rings, head gaskets, fresh valve job, and resurfaced decks.

A built Viper V10 from a high performance shop (Arrington, Calvo Motorsports, Roush) targeting forced induction or 800 plus horsepower naturally aspirated runs $25,000 to $50,000 plus. Built makes sense for boosted Viper builds, drag racing applications, or extreme high horsepower swap projects.

Condition and Inspection Process

• Compression test across all 10 cylinders, pressure per cylinder recorded
• Visual inspection of block for cracks, deck damage, and cylinder wall condition
• Generation and displacement confirmed via casting, head, and intake identification
• Exhaust manifold condition documented (Viper signature crack issue)
• Cylinder head inspection for cracks and head gasket sealing surface
• Cam sensor and crank sensor condition disclosed
• Donor vehicle and mileage disclosed where available
• Visual valve cover inspection for sludge and rocker condition

Mileage on Viper V10s is documented from the donor vehicle when available. Many low mileage donors come from collector cars with very low miles. Where mileage cannot be verified, we disclose this clearly before shipping.

Buyer Tips, What to Know Before You Order

• Confirm generation and displacement first. 8.0L, 8.3L, and 8.4L are not interchangeable without supporting work.
• Cracked exhaust manifolds are nearly universal on Gen 1/2 cars. Plan for stainless headers (American Racing, Belanger) at install. Do not pay extra for a unit with intact factory manifolds, they will likely crack again.
• For Ram SRT-10 truck swaps: Use Gen 3 truck calibration if possible. Truck and car ECUs differ.
• Swap projects: Viper V10 is heavy and long. Plan for a strong bell housing adapter, custom mounts, and a cooling system upgrade.
• ACR engines are premium. If you find one priced like a base SRT engine, verify casting numbers and donor history carefully.
• Plan for new spark plugs (10 of them), all coil packs, and a complete fluid service at install regardless of unit condition.
