This made me wonder if they made a similar cast manifold for the GE?

And low and behold:

But does it fit in the sc300 engine bay?

Almost looks like it would be more distributor friendly as well.

wow that manifold is awesome, exactly what i have been searching for a while now.
couldnt find a low profile cast manifold for the ge, and this is undivided so you can use a QSV, I would definately like to hear more about this. Is300 bay is narrower than a sc bay, the only problem i would think would be the distributor, but you could use a spacer (or a QSV) to add some extra clearance, or just delete it.

HiPSI

Exactly, the QSV would actually help in this scenario, as well as no heat or clearance issues with the upper intercooler pipe near the throttle body because the manifold aims the turbine housing down not up.

I tried searching for any feedback on this forum, supraforums, and even my.is forum and nothing, nobody really has used it or talked about using it.

Also found this:

You could always fabricate your own utilizing enough space for the QSV.
