* Condition of the Engine: A slightly worn engine needing minor work will be far cheaper than one requiring extensive repairs or replacement of many parts. A seized engine, for example, will be much more expensive.
* Parts Used: Using remanufactured parts will be cheaper than new parts. High-performance parts will significantly increase the cost.
* Labor Costs: Mechanic labor rates vary significantly by location and shop. A specialized shop with highly skilled mechanics will be more expensive than a general repair shop.
* Scope of Work: A simple rebuild focusing only on essentials will be less expensive than a complete rebuild with blueprinting, balancing, and performance upgrades.
* Additional Services: Things like machine shop work (e.g., block decking, crank grinding) add to the cost.
To get a more accurate estimate:
* Get multiple quotes: Contact several reputable engine rebuilders in your area and describe the condition of your engine and the desired outcome.
* Provide details: Be specific about any known problems with the engine. Mention if you have specific parts in mind.
* Clarify the scope of work: Discuss exactly what you want included in the rebuild. A written quote outlining all work and parts is essential.
In short, without knowing the specifics of your 350 engine and the desired rebuild, any price given would be a rough guess at best. Get professional quotes to get a realistic cost for your specific situation.
