I translated and summarized the following for an RV-7A builder in Italy named Lucio. He acquired a used Lyc IO-360 A1A in parts (no history or other info given), and a trusted mechanic can rebuild it for 8K euros. He would like to know if this type of Lycoming is a trustworthy engine for the RV-7A in general, any historical problems with it, etc. Also he would like to know if it is worth rebuilding this engine vs. buying new from Van's. With devalued dollar, he can get a new engine cheap, BUT with high transportation and import taxation costs, it would add up to 22k euros (north of $30k). 



OK, my take on this:

Can't tell much about whether the used engine is any good from his note. Crankshaft OK? History of damage/prop strike? TT and TT SMOH? Why is it in parts? Corrosion? Camshaft OK? Any AD's on the parts/crank that need complying with? Basically, I would advise to have the engine inspected by a knowledgeable mechanic first, before agreeing to a $12k rebuild. There are many stories of these used engines ending up costing far more than a new one when everything is done. Since this engine is in parts, it will be much cheaper to inspect than doing a teardown.

As to the IO-360 A1A engine and the RV-7A, it is a popular combo (more as in the carburetor configuration) and would be an excellent powerplant capable of meeting Van's published performance speeds at fuel burns near 8 gallons per hour lean of peak with the fuel injection. Any other thoughts from group? 

Thanks,

Carl
