* The specific engine: Different V8 engines (e.g., a Chevy 350, a Ford 302, a Chrysler 318) will have different parts costs and labor requirements. The more common the engine, generally the cheaper the parts.
* The condition of the short block: Are you providing a core (your old engine block)? A rebuild using your existing block is cheaper than starting with a new block. The condition of your core engine will affect the labor required, as well.
* The extent of the rebuild: Are you rebuilding the entire engine, or just doing a top end rebuild? A complete rebuild includes replacing bearings, rings, seals, gaskets, etc., and is significantly more expensive than just replacing heads and valves.
* Parts quality: Using new, high-quality parts will increase the cost, while using remanufactured or used parts will lower it. This affects reliability and longevity.
* Labor costs: Labor rates vary wildly by geographic location and the shop's reputation. A smaller, independent shop will likely be less expensive than a dealership.
* Additional work: Any additional work required (machining, balancing, etc.) will also increase the overall cost.
Rough Estimates:
You could expect to pay anywhere from $3,000 to $8,000 or more. A lower-end estimate assumes a used, less intensive rebuild using some remanufactured parts and potentially your existing engine block as a core. A higher-end estimate reflects a complete rebuild using all new parts and potentially needing extensive machining.
Recommendation:
To get an accurate quote, contact several local automotive machine shops or engine rebuilding specialists. Provide them with the year, make, and model of your van, as well as the specific V8 engine it has. Be sure to discuss the extent of the rebuild you're looking for and ask about their labor rates and the parts they'll be using. Getting multiple quotes will help you compare prices and services.
