Continental engines are built with the best components in the industry. The only parts we paint are the steel barrels to resist corrosion. All aluminum parts; crankcase, assembly case, sump cylinder heads and assy drives are alodined only for corrosion protection. This leaves an engine that is easy to inspect, provides better cooling, and is lighter weight.
I ordered this and my credit card was rejected for the shipping address was wrong. I went to my shopping cart and the product wasnt there so I ordered it again. I now have two sets. Id like to return one set.
