Bob,
You are looking for a late 1967 or early 1968 dated 289 hipo block. Casting number C5AE-E, also may have orange paint on rear of block as an identifier.
Seriously, I doubt that you will ever find one with all the correct parts you would want, intake, heads, distributor, harmonic balancer. This would have been sold over the counter at Ford for the most part.
If you really want to build something "close" to it, use a Mexican 302 block, and then add all the rest of the external parts. I have a short block assy currently, but it is dated 1970 I believe.
Otherwise, your 72 engine will go just as good....in the mean time. Otherwise you may never get the car rolling again! IMHO!
