You could probably use a big carb manifold e.g. an edelbrock or offenhauser, or use an old SDi manifolds and cut off the SU mounting area. Then make up an adapter plate out of aluminium plate so you can bolt the supercharger down. The plate will have to be quite sturdy to take the weight, vibration and torque from the blower.
The main difficulty I forsee is getting the air distribution even enough to all 8 cylinders so you get an even mixture. With the supercharger outlet mounted so close to the manifold the air is likely to be turbulent. You might add some baffles into the adapter plate, and/or maybe a sheet of honeycomb alloy, to make the flow laminar and even.
The Eaton was certainly designed to work in this position though:

The other question is will the nose stick out far enough so the pulley is over the front of the engine, but I'm sure that can be solved (even if you have to bolt another pulley onto the existing one - actually this might be a better idea 'cos you can then use a toothed belt and pulley - much better for traction.)

Found this last night which was more what I had in mind.....
Not sure about putting the coil packs next to the sump tho !
