BD15 is one of my favourite cams we used it extensively in our 1980's touring car engines along with a bd14 exhaust cam with very specific secret squirrel cam timing figures
fast road engines we used different exhaust cams
The infamous dessert storm of that era ran the 15 14 combination
from the early 1990's we used modified bd15's as well as 16's
the most commonly used cams for fast road engines by us were those very trick expensive std ones that came free with the car
