Spica intake manifold, 1750 vs 2000?

[Kevin Trent <trentkc@domain.elided>]

I'm at a decision point in my 1750 rebuild that will be Spica injected with 
a T-255 pump from a '73:  whether to use a 1750 intake manifold or a 2000 
intake manifold.  The 1750 intake has smaller ports on the head side, 
approximately 33x41mm while the 2000 has ports noticeably larger at 
37x44mm.  When I test fit against the head the 2000 manifold is obviously a 
better match to the cylinder head port.

My concern is that the large port of the 2000 intake may be detrimental to 
low end responsiveness.   I'm using a 11mm 300 degree intake cam and euro 
10548 exhaust cam set at 102 lobe centers.  This intended as a street 
engine for a Berlina.

Anyone have any experience with such a swap?  Are 1750 and 2000 Spica 
injectors the same?
