#'s matching
i'm a little confused on the numbers matching game. i read some previous posts saying that there are no numbers on the engine before 68. I've got numbers on my engine that are C5OE-9425B, which i looked up and said it's for a 66' fairlane because of the o, mustang's have z. i've got a 65' 289 2 barrel, is this not the original engine or could they have swapped it out at the factory, or are these numbers not important?

AFAIK, the early engines were corporate and none had "z" in them for mustangs. I beileve there's a link in the FAQ section of the forum that you can verfiy this fact.
Here's the link to that page:

A little clarifacion--First Ford engines at least thru 1977 used an engine tag with was stamped metal about 1/2 inch x 1 1/2 inch and mounted under the coil bracket. This gave all pertanent info about the engie including a number which indicated it's intended application.
Second - Ford has two numbering systems. The numbers which you find stamped into or cast into components are engineering numbers--These are the numbers created when the part is designed or redesigned and which engineering and parts vendors use.
They will not translate into a dealer's part number since the Parts division creates them into a sales number. They might for example decide that Carburators which bear 10 different engineering numbers are so similar that they can create one Carburator to use as a replacement for the 10-Therefore there will be only one sales number. A Ford parts catalogue will identify all the various codes etc that a particular sales number will replace.
Confusing? Yes.

the number that is cast in the block on pre 68 mustangs just tells what type of car it goes into, on 68 and up the VIN is stamped on the block as well as the casting number. when a 68 and up car is matching numbers that means that the vin on the block matches the vin on the door and the dash. hope this helps. and i think z is for mustang, any year

RE: #'s matching
Numbers matching can get very deep. Not only do you need to have the correct part number (engineering number usually in the mold), also theproduction date of the part needs to be correct (usually stamped or taged).The third element is,normally the VIN is stamped into the block as well and maybe eventhe transmission case (as stated before), these need too matchthe sequencial production number of the car (the last six numbers).Thats why a truely "matching numbers" car is very rare.

Didn't Ford lose all the documentation on 64-66 mustang so there is no way to prove its numbers matching, even a Marti report can't show it. This is what I understand, if I'm wrong please someone correct me.

RE: #'s matching
well apparently my engine isn't numbers matching since it's got an o in it and that's supposed to be for fairlanes. i guess they might have installed a fairlane into a mustang if they needed to at the factory, guess there's no way of knowing
