For the new WISSOTA crate engine they are paying from $3000 to $3500. The only problem with these engines is they are stamped and you cant work on them yourself. You have to send them away to a WISSOTA builder. If you go the other route I brand new wagamon engine is running anywhere from $5000 to $8000. Or for your engine to be freshened it is about $6000. We are on our 3rd engine being built right now. The last 2 saturdays we blew up good.
