The casting number on my engine block reads
0 C5AE-6015E and above it is 6F6.  I know this is a 1965 289, but what is do the other numbers tell me?  Thanks.

That block does NOT match the block for a 64 1/2 Mustang.

How about the heads and intake ?

Numbers decoded


C - Decade = 60's
5- Year the part was designed for (1965)
A- Car line is was designed/engineered for ( A = Galaxie)
E- Division of design - Engine Division
6015- Block engineering ID number
E - Change up code.( could mean there were 4 versions of that block before that one.

*6F6* tranlates to

June 6th 1966

6 - year of casting
F- Month of casting ( A being January)
6 - Day of casting.

Never heard of this O Wink
