In market the kabli engines are difficult to fined, and if you are lucky enough to see one, it will be around 2,20 or 2,30. Civil engines are worth 60 to 70,000. Luckily a good friend recently general overhauled his 3b with all japanese parts but later decided to go for a 6 cylinder engine thus sold it to me for 1,20. Its in mint perfect condition. Thermostat valve fixed, zero blow, like a brand new engine.
