BBC cog drive system- Black Mountain Precision
 

F/S one Black Mountain Precision cog drive, bracket, and belt for BBC with a short water pump. Made by http://www.blackmountainprecision.com/ . I have approx. 500 miles on this system without any issue. It certainly was the answer to my belt throwing issues under big RPM. I had it all powdercoated semi-gloss black. Over $450 new before coating- $200.
