Justin,
I would guess that you are aware that motorcycle streamliners are now under car streamliner rules and will be teched by both m/c and car inspectors?
From 2009 rulebook:
5.A SPECIAL CONSTRUCTION CATEGORY
This category is the pinnacle of the straightaway racer’s art. It contains three main groups. In the automobile group are the unlimited Streamliners and open-wheeled Lakesters with a 4+ wheel configuration and in the motorcycle group are the streamliner and streamliner sidecar class. These classes allow both blown and un-blown, gas or fuel engines. These are all-out straightaway vehicles with non-stock engine blocks allowed, (with the exception of specific Vintage Engine classes). Innovation is unlimited. Modified production bodies are forbidden. Four-wheel drive is allowed in the automotive group only.
