That depends on what the shop would charge for labor, or if you are doing it yourself.
You will need quite a few things like different motor mounts, a new transmission, exhaust manifolds or headers, a custom driveshaft, and more than likely some work to the rear end. And of course, the 302.
It is quite a large project, but it can be done.
