Inliners International Forums General Discussion Engines 230 Inline 6

To make it into a 250 you would need to swap out the crank and the pistons.For what your building the 230 would probley be just fine. So my 2cent is take what money you'd put into makeing it a 250 and put it into your ride in other areas.
So unless your after more cubes & HP i'd say build what you have
already.
