There may be multiple listings on our site that fit the same model engine but due to the technical nature of engine kits, the correct application and fitment is decided by engine serial #. If it is determined that you will need a different engine kit and there is a price difference, a member of our team will contact you to see if you still wish to proceed. We will do our best to make the buying process as easy as possible for you!
