Just kidding, it's either an A6 or an R4, axial or radial. Radials are inherently noisy, more so when under r134 head pressures.
The best solution is a Sanden SD508 + bracket kit and hose retro-fit, but it's not for everyone. Alan Grove made my adapter brackets (https://www.alangrovecomponents.com/Small_Block_Long_Pump.htm), I made the hoses. It's a lot quieter, and far more efficient.
