Fuel injection for the slant six

Tim Keith said

I have an Offenhauser 2 x 1 intake. A GM 4 cylinder TBI unit has the same base size. I think 2 TBI units could be used on this manifold. How was the fuel distribution of this manifold with carbs? I've not heard many good things about performance other than that the Offenhauser 2 x 1 looks good.

This is just a swag, as I have never ran the Offy 2x1 intake,
But I would think that the 2x1 would act like a dual plane intake, have better vacuum response due to less valve overlap at each carb opening.
While the standard single carb opening slant intake would act more like a single plane intake, because it is.
Again, I would bet that 99% of it is in the tune with either setup.
