How can I find the year my 460 was built?
the casting number will tell you what general year block you have...
it'll be on the passenger side below the heads, above the starter...
You will have to look under the valve cover to determine the day it was cast
The part engineering # will only tell you a basic code and what the change up number is.
Details are details![]()
about the only two #'s that mean anything, and they don't mean much, are the head casting number and the block casting number. d1ve blocks were around from 1970.5ish to 1978. after that it went to d9ve. heads are most likely d3ve's, but could also be d0ve's, or possibly c8ve's.
i assume you have d3ve heads and a d1ve block. pretty common motor.
head is right below where the valve cover ends. block is right behind the third freeze plug, flywheel end. had to go look in teh garage. bad memory.
are you looking in the right spot? i've marked my photo to show where to look:
![]()
and what you find should be a group of numbers and letters something like this:
![]()
xxxx-xxxx-xxx, should be something like c8ve-xxxx-xxx,d1ve-xxxx-xxx, or d9ve-xxxx-xxx. if you can't read it clearly try to take a piece of paper and a crayon or pencil, and etch over it. should be a little clearer to see.
i'd be willing to bet it's a d9ve block because the first letter has a flat back like the d's. the c's are nice and round in the castings and the second mark has too much to it to be a 1.
