There are basically five factory camshaft grinds:

  • small bore grind
  • large bore grind
  • GX grind
  • Performance grind for A12T, A14T, EFI
  • Hi-torque emission grind (1981-1982 USA)

However, these can be fitted to any engine. The emission grind cam was used in A12A, A14 and A15 engine -- all with same cam part number.

Duration

"Advertised Duration" means you should only compare these numbers with grinds from the same manufacturer. Other vendors may measure it differently.


Early vs. Late

For 1974, the A-series engine was re-designed. Because the distributor moved from beside cylinder #1 to beside cylinder #3, a new gear was added to the cam. The oil pump eccentric was moved from #3 to #2 at the same time.

Competition Camshaft

Beware, some cams have no eccentric cam for the fuel pump. You will have to use an electric fuel pump with these cams.
