am planning on building a 550hp - 650hp yb and have come across the problem of
which inlet manifold to use, have seen and like the look of the mis inlet manifold but
from various threads on here have seen they only like being on engines with 700hp+.
as i live in new zealand "expert" advice is thin on the ground and my only option is
asking abroad for advice so any would be greatly appreciated.

I'd imagine anything with decent flow, and a decent sized plenumwould work just fine.

As nearly all setups have a straight shot from plenum to valve anyway, just get a plenum with a reasonable amount of volume.
