Hello from Chicago! Our club recently built our Tost winch from a kit and the engine Tost reccomends is the Chevrolet 454 HO. It is still in production and in the USA is easy to find at all major online auto parts suppliers. We bought ours from Jegs for about 5500 dollars. Your challenge is going to be the shipping. Do not buy from Tost or Skylaunch! Why ship an engine from Detroit to Europe to Japan? Order from the online source who will ship for the lowest cost.
