81-82 12A Engine Numbers
These are the Part Numbers for 81-82 12A Engines. These are just the majority of the ones we list. We are able to "build" about any combination possible with our computer -- just give us specific requests, and we can come up with a pretty exact estimate of the cost.
The "Build Level" chart is at the bottom of the page
Note: Core supply is variable, please call prior to ordering your engine.
For 81-82 12A engines the cost of a full gasket set is included in the price of the engine. We use the gaskets/seals needed to assemble the engine, and send the remaining ones with the engine - that way you have essentially all the gaskets needed to finish the installation.
