Mancini manual steer box?

Anybody ran the Mancini racing manual steering box? Can't find any reviews of it really. And yes I tried the search function and didn't see any useful info. Just looking for general info on quality/fitment etc. I'm running a small block with tti 1 3/4 headers, it's a street car but it will definitely see some quarter mile passes. Looking to ditch the boat anchor power steering setup.
