need tri power dimension on a chevy

I need the dimension from carb center to carb center for a tri power intake, either an Offy or Edelbrock for a small block chevy.
My dilema is that I have 3 carbs but they have front inlets with 90 degree fittings. Used on a Olds manifold there is no problem but I think if used on a Chevy they will interfere with each other.
Pictured below is what I have.

Thanks

 

Hey Mad...didja forget one of your club members has a chevy with tri-power????

All you have to do is come to this side of town and take all the measurements you need....
