You'll still have to spend additional money with the crate. but just might start as a foundation if you end up looking for more HP. With the 289, you most likely have 28 oz balance components, and the crate is 50 oz, so you will probably have to change your flywheel. New oil pan because it comes with a front sump and you need a rear sump. New distributor or a new gear on your current distributor because of the cam. The iron heads are a choke point, but that can be overcome at a later time. Depends on what you want to do. Picture shows a carburetor installed and listed as coming with the engine, but then it lists a carburetor as a recommended component. Definitely would have to call on this one to make sure what's included. And not available to ship until the end of July.
