I thought I would share information I gleaned from the 1960-64 MPC and the 1961 ready reference catalog,the 60-62 352/390 used in galaxies and T-birds with 2B and 4B carbs used a hydro cam part number C0AZ 6250 A,60-61 Galaxie only 352/390 4B only used a C0AZ 6250 B cam(I suspect this one to be the HP/Special cam cast letter K).61-62 police 390's used a C1AZ 6250 B solid cam,62 Tbird 6B used a C2SZ 6250 A hydro cam and 63 Tbird 6B used a C3SZ 6250 A hydro(I suspect the 2 Tbird cams are the same profile 62 on the early thrust button core and the 63 on a later non thrust button core).The 62 390HP/early 406 used the C2AZ 6250 A (mechanical tappets cast letter K stamped letter A I believe this cam to be the same as the 60-61 cam except for a revision on installed timing).Then late 406 used a C3AZ 6250 D cam cast upside down A B(I believe this cam to be the AA profile on an early thrust button core used with 4B 6B and 8B and long exhaust manifolds).Then the 63-64 427 used the C3AZ 6250 AA cam upside down A BA.There is also the C4AE 6250 B cam that is the long duration cam for use on high performance vehicles(lightweights and Tbolt?).
