Seriously though, the duke will never be a performance engine. Minimal power gains will be acquired through maximum effort.
Sure, you can spend a lot of money and have a little bit more fun... until it blows up.
Just be content to have your duke running properly, until perhaps you wish to swap in a different power plant.
