6-71 Supercharger/harmonic dampener question

Hey guys, seeing we don't have the "Forced Induction" page here anymore, I hope those running 6/8-71 blowers can help guide me in the right direction?

1969 440/RB 6-71, I'm running a narrow 2 groove accessory crank blower aluminum spacer pulley to have PS/water pump and alt, along with the 3" belt drive, drive ratio is 1 to 1 (34 tooth approx 6" dia. IIRC)question is the balancer, run a new stock internal/neutral unit or a fluid unit?, if so, what brand/style?...cost is no issue, just quality/correct application is.

I feel the added weight along with the increase in tension and leverage on the crank snout may not be ideal for a factory style dampener?, or am I over thinking this?

I would like the dampener thickness to be in relation to the factory thickness due to space/alignment issues

Thanks
Mike
