I use the BJ /BK
By Royce - 04/10/2005 9:56:13 AM; IP 4.225.156.253
The BC / BD's are not much different. If you are buying new ones the BJ/BK's are better for a street application.

The old timey Fomoco cam grind is a poor choice in my opinion. Lots of newer grinds by Comp Cams or others will get you better street manners and more horsepower. Those old factory grinds had low lift, tight LSA and long seat - to seat duration. Modern cams have steeper ramps, wider LSA and more lift for better cylinder filling so while seat - to - seat numbers might look similar the .050" numbers are way different.
