Federal Power Steering Pump Pulleys

Hey fellow Mopar brothers and sisters:
Other than perhaps looking a little weird, would I run into any issues using the Federal Pump with correct bracket from my 225 '75 Scamp when I swap in the 383?
The Slant 6 PS pulley is 6 3/4" and crank pulley is 6 1/4 I believe.
I've been looking around for smaller diameter pulleys like 3751556, and people want a FORTUNE for even a '75 era 400 4Bbl PS pulley for a Federal pump.
