Hey Brian! We are working on the V71 series first (and as we speak, actually!). But, we do have plans to do the inline 71 series as well. Since most of the parts on these engines are modular, it will really just be the blocks and a few other parts that will need to be reworked. But, just to give you a realistic expectation, it will be into next year before we are working on the Inline series.
