Why Buy a Used Dodge Engine from Auto Power Source
Dodge's engine catalog is unusually broad because the marque shares the FCA/Stellantis engine bin with Chrysler, Jeep, and Ram. That cross-pollination is great for parts availability but treacherous for swaps: the 5.7L HEMI in a 2009 Ram is mechanically distinct from the 5.7L HEMI in a 2014 Charger because the Eagle revision in 2009 added VVT and a different intake and cam profile. The Pentastar 3.6L V6, introduced for 2011, replaced the venerable 3.7L Magnum V6 entirely and is shared across the FCA range — but it has its own pre-2014 head issue and a post-2014 revision. SRT engines (6.1L SRT8, 6.4L 392, and 6.2L supercharged Hellcat) are dedicated performance variants and never interchange with the truck HEMIs.
Our 2,014 Dodge engines all come from low-mileage donor vehicles, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Each unit clears our six-step process: VIN-matched to donor and target, ASE-certified compression test on every cylinder, leak-down evaluation, run-stand noise & smoke verification, full visual inspection of the long-block plus turbos and manifolds where present, multi-angle photographs sent for your approval, and palletized freight shipping. The Cummins diesels get extra checks: injector pump pressure, turbo shaft play, and grid-heater function.
You pay a fraction of dealer-new pricing for identical FCA engineering, ship free on a heavy-duty pallet to any address in the continental U.S., and you have 30 days from delivery to return for any reason — no restocking fees, no return freight charges. The warranty printed on the listing — with extended coverage up to 3 years available — covers you after install, and our six-step inspection has held our fitment-related return rate at 0% across 100K+ engines and transmissions in stock.

Dodge Engine Buying Guide
5 things to verify before buying a used Dodge engine:
-
5.7L HEMI: 2003-2008 (non-Eagle) vs 2009+ (Eagle with VVT). Pre-2009 and post-2009 HEMIs are not direct swaps — the intake, heads, and cam timing all changed. Confirm the year split before purchase; this is the single most common Dodge mismatch we see.
-
Pentastar 3.6L: 2011-2013 vs 2014+ revisions. The 2014 Pentastar revision addressed a cylinder-head and valve-seat issue on the early build. Confirm which generation a long-block came from before ordering.
-
Cummins 5.9L vs 6.7L are completely different platforms. The 5.9L 24-valve (1998.5-2007) and the 6.7L (2007.5+) share the family name but not parts. The 6.7L brought EGR and DPF on most years — confirm emissions state and tune compatibility.
-
SRT engines are not interchangeable with truck HEMIs. The 6.1L SRT8, 6.4L 392 and 6.2L Hellcat have forged internals, unique calibrations and dedicated accessory layouts. A 392 will not drop into a Ram that came with a 5.7L.
-
Confirm the match with your own VIN before you order. Your VIN settles the engine code, drivetrain and build split in one step. Text it to +1-307-441-5554 and we will confirm in writing exactly which unit fits your vehicle before you pay.
Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.
