engine identification

[k_fastback]

I have recently pulled a 1964 Hipo 289 small block out of a boat. It has the Cobr pan, Cobra intake, Cobra valve covers. The block casting number is c3oe-f and the heads are c3oe. On the back side of the engine below the left head is a stamped number 5478 and there is also a number stamped in the block on the front left head mating surface. Could any body tell me if there is any significance to those numbers? Thanks

K_Fastback,

One possible breakdown according to my charts.

C3OE

C= decade===1960
3= year===== 3 therefor a 1963 block
O= Fairlane
E= Ford Engineering Department ( Engines )

I am sure some of the others have a more complete breakdown and I don't have anything in my stuff about the # 5478.
