Cool project man! If you end up having issues with tuning try to switch that spacer for a open center style one. I personally have never ran anything like this but some guys have had problems with the TBI style fuel injection not liking the 4 hole style spacer, seems they like to spray into an open plenum type of deal to mix the air and fuel or you end up with some odd dips and spikes in AF ratio and power.

EDIT: you might be fine, just saying if it seems like your having fuel issues try the spacer before thinking its the whole EFI setup.
