Why Buy Dodge Engines 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/cam profile. The Pentastar 3.6 V6, introduced for 2011, replaced the venerable 3.7L Magnum V6 entirely and is shared with Wrangler, 300, Grand Cherokee, Challenger and Promaster — but it has its own pre-2014 head-fit 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 1,180+ 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. Up to a 3-year warranty covers you after install, and our six-step inspection has held our fitment-related return rate at 0% across 46,000+ shipments.

Dodge Engine Buying Guide
The 2008-09 split is the trap most Dodge engine buyers fall into: Chrysler revised the HEMI mid-cycle with the Eagle update, and even within Pentastar production there are pre-2014 and post-2014 variants you should not interchange. Five checks before you order:
-
Match the engine code by VIN 8th digit. On Dodge VINs the 8th character is the engine code — get it from your title or door jamb sticker.
-
For 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 year split before purchase.
-
For Pentastar 3.6: 2011-2013 vs 2014+ revisions. The 2014 Pentastar revision addressed a cylinder-head/valve-seat issue. Most reputable sellers note which generation a given long-block came from.
-
Cummins 5.9L vs 6.7L: completely different platforms. 5.9L 24-valve (1998.5-2007) and 6.7L (2007.5+) share the family name but not parts. The 6.7L brought EGR and DPF on most years — confirm DEF state and tune compatibility.
-
SRT engines (SRT8 6.1, 392 6.4, Hellcat 6.2) are not interchangeable with truck HEMIs. Dry-sump variants, forged internals, and unique calibrations make these dedicated performance long-blocks.
Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.
