This is going to sound complex, but there's another way to disconnect the blower discharge position from the length to the pulley, but it's only good for blow-through.
1. locate the blower case so the pulleys line up as usual.
2. rotate the blower 180° so the exhaust faces up.
3. make a cover for the discharge port using the gasket surface and whatever bolts are available, with a 2" long 3" OD cylinder stub over the end of the triangle.
4. 3" 90° bend to a straight 3" tube
5. tube angles away from the blower (not straight across) to align with a normal 4 bbl. manifold inlet (Clifford, etc.)
6. tube enters the carb hat or box from the side

3" is just my guess (same area as a 4 bbl. with 1-1/2" venturis), but since it's dry it doesn't matter. It would be a problem if draw through carb.
