4bbl carb question

I don't know if the aftermarket intake flows more evenly than OEM but ...
The center cylinders have always ran richer than the end cylinders due to the tube length with stock manifolds.
The fuel is atomized better at the center cylinders too.
There was a guy at slant6.org who put together a fuel injection setup for that manifold. I dont know if it was completed and/or how it performed. Even with exact fuel delivery from injectors the air flow would be a little uneven if the tube diameters aren't staggered .
