That hood works with a crab and round air cleaner. But if you go with a long plenum fuel injection unit or blow through carb hats, clearances become an issue. That is why I have the Harwood fiberglass over the steel Harwood. The Harwood didn't fit with my combination. I'm sure it is fine for most applications and certainly looks well made. Hopefully ease of fitment is as good as they say. I would have preferred a steel hood. Guess we just have to wait for Scott to put his on and post his experience.
