What You’re Getting

This is a complete, used engine assembly pulled from a 2021 Dodge Challenger. It’s the 3.6L Pentastar V6 (VIN G, 8th digit), configured for Rear-Wheel Drive (RWD). The donor vehicle had approximately 85,000 miles. We’re selling the long block assembly. This includes the engine block, cylinder heads, valve covers, oil pan, timing cover, and all internal rotating components. It does NOT include accessories like the alternator, starter, power steering pump, intake manifold, or exhaust manifolds unless pictured. What you see is what you get.

This isn’t a mystery crate from a junkyard. We sourced this from a known vehicle, gave it a visual and mechanical inspection, and tagged it. It’s a direct replacement for your 2021-2023 Challenger with the same VIN G 3.6L RWD setup. The part number you need is 1002379621.

Why This Engine Solves Your Problem

Your Challenger is down. Maybe it threw a rod, spun a bearing, or cracked a block from overheating. You’ve got two real choices: a multi-thousand-dollar rebuild with machine shop delays, or a used assembly. A rebuild is a gamble on labor and hidden costs. A cheap, no-name used engine from an auction site is a bigger gamble.

This engine is the middle path that makes sense. You’re getting a known OEM Pentastar that lived its whole life in one car, designed specifically for your model. Swapping in this complete assembly is the fastest, most cost-effective way to get your Challenger back on the road with factory reliability. You’re not paying for a full turn-key crate engine, and you’re not risking a shoddy rebuild. You’re buying a solid, tested core to build upon.

Our Process: No Surprises

We don’t just list parts; we verify them. Here’s what we did:

• Vehicle Match: Confirmed this came from a 2021 Dodge Challenger RWD with the 3.6L VIN G engine.
• Mileage Verification: Documented the odometer reading at time of pull (~85K miles).
• Visual Inspection: Checked for major external damage, fluid leaks, and impact cracks. No visible holes or catastrophic external damage.
• Core Integrity: Manually rotated the crankshaft. It turns freely by hand with no binding, and we verified there’s no obvious internal seizure.
• Tag & Bag: The engine is tagged with our stock number (TX203647) and core info. It’s drained of fluids, wrapped, and secured on a pallet.

Important: This is a USED assembly sold as a core. It is not rebuilt. While it passed our basic mechanical and visual inspection, we cannot guarantee internal components like piston rings, bearings, or valve seals without a teardown. We strongly recommend a professional inspection upon receipt before installation. This is standard industry practice for a used long block.

The Fine Print You Need to Know

• Compatibility: 2021-2023 Dodge Challenger with the 3.6L V6, VIN G (8th digit), RWD. DO NOT use for AWD models or other VINs (like VIN 7). Verify your VIN and configuration.
• Condition: Used, untested beyond basic inspection. Sold as a core/assembly.
• What’s Included: Engine long block assembly as described and pictured. Accessories shown in photos are included; if not pictured, they are not included.
• Core Charge: A core charge may apply and is separate. You will receive instructions for returning your old unit.
• Shipping: This is palletized freight. We ship nationwide. You’ll get a quote and timeline before you pay. It ships to a business or commercial address with a dock or forklift for easier unloading. Residential liftgate service may be available at extra cost.
• Warranty: This part is covered by our standard 30-Day Exchange Policy. If it arrives damaged or is found to be defective (e.g., cracked block, seized internals) upon your professional inspection, contact us immediately for an exchange. No returns after installation.

Who Should Buy This

This is for the professional mechanic, the skilled DIYer with a shop and tools, or the car owner working directly with a trusted technician. You need to know how to handle an engine swap, transfer components, and perform the installation. You understand this is a core assembly and will plan accordingly—replacing seals, gaskets, and inspecting components during the swap is expected and smart.

If you need a plug-and-play, fully dressed engine with a warranty, that’s a different product at a much higher price. This is for the person who wants a verified, correct OEM foundation to work
