I did try paralleling 2 of them, better at startup then WAY too much air too
soon, doesn’t track properly.

I'm pretty sure there were other cars, with engines bigger than 1600, that
had larger AARs. Consider Volvo or Saab, for example. Perhaps you could
plumb in one of those.

FYI, our '73, and perhaps also our '72, IAD have a larger AAR inlet than the
earlier ones, not because they had a larger AAR, but because they had a
vacuum limiter piped into that same port. The larger port might make it
easier to use a larger AAR, or perhaps you could parallel an MT and AT Type
3 AAR.
