* Which Hemi? The Hemi family has many variations (e.g., 5.7L, 6.1L, 6.4L, supercharged versions). Each engine will have different costs for the engine itself, plus potentially different requirements for installation. A used 5.7L will be significantly cheaper than a new supercharged 6.2L.
* New or Used Engine? A new engine will be considerably more expensive than a used one, but a used engine carries more risk (potential issues, unknown history).
* Parts Needed: Besides the engine itself, you'll need a new transmission (likely, depending on the original engine and the Hemi chosen), engine mounts, wiring harness modifications or replacement, possibly exhaust system modifications, computer reprogramming, and potentially other parts. Some parts might be adaptable from your existing setup, but others will be mandatory.
* Labor Costs: This is a major expense. A professional mechanic will charge several thousand dollars for the labor involved in the removal of your old engine, installation of the Hemi, and all the related modifications and adjustments.
* Installation Location: Shop rates vary regionally. A specialized muscle car shop will likely charge more than a general mechanic.
Rough Estimate:
Without knowing specifics, a *very* rough estimate (using a used 5.7L Hemi and assuming some parts are reusable) could range from $10,000 to $25,000 or more. A complete swap with a high-performance Hemi and all new parts could easily exceed $30,000.
Recommendation:
Get several quotes from reputable mechanics specializing in Dodge vehicles or muscle car restorations. Provide them with the specifics of the Hemi engine you're considering to get accurate estimates. Be sure to ask detailed questions about what the quote includes (parts, labor, warranty, etc.). Don't forget to factor in the cost of fluids and other consumables needed for the engine's operation.
