More than anyone probably wants to know but according to my old Isky booklet:
Grind 02A (3/4) Cam
Road grind for passenger cars. Provides an increase in acceleration at speeds
above 15mph. Idles smooth and quiet. Recommended for stock or slightly
over-bored passenger cars with standard or automatic transmission. The widest
range
3/4 cam in the world which still retains desirable low-end characteristics.
Increased compression and carburetion recommended for best results.
Then it goes into the Rev-master Cam (full race),Big Full race and Super full
race grind descriptions. Booklet is Circa 1958.
