Carb and Intake for 5.2 Magnum

I am doing a custom build with a Magnum 5.2 and 46RH OD trans going into a 1960 Studebaker which i bought with no engine, a rare find here in Spain. I bought a running 93 Cherokee as a parts car that had failed the annual inspection so drove it around on dirt tracks to check the engine before i pulled it out and it ran really good so i have no intention of doing any unnecessary work on it.
As its in a 60's car i i thought it would look better with a carb as i've already fitted V-belts, what i've found so far is a Speedmaster 1-147-028 intake, Holley 0-80457S 600 CFM and proform 440-426 distributor. What i'm looking for is similar performance to the MPFI i'll be replacing and similar fuel economy as gas is expensive here. Would be interesting to know what combinations people have fitted for a street car.
