What's the best way to measure how tall your air cleaner housing can be? I swapped out the intake manifold to one that's 1" taller, so I know reducing by 1" would work, but If I knew there was some wiggle room in there and only needing to modify the cleaner housing by say 3/4" would work, that would be better. What have you guys found works best as a way to measure height from top of the carb to the ram air panel under the hood??
