Numbers on 65 390 engine not matching up????
Got a few simple questions that I hoped maybe some of you had either seen before, or had some more knowledge on.
First off, I am a very knowledgeable car guy and have been around fords all of my life.
I just bought a 65 Galaxie 500 convertible that should have a 390 motor in it accordining to the warranty tag on the door and the "Z"code. I know that all FE blocks are stamped 352 and are not discernable to cubes or size by any outside markings, as is the case with my motor also. I have taken the motor completely apart, measured the stroke at 3.75 (or greater depending on my wonderful measuring skills), and have also verified that it is a TRUE 390 as it is marked on the first lobe of the crank "390".
My confusion comes with this...... The date codes on many parts of the motor just don't jive with a 65.
The carb is dated correct at C5AF-AL.
The tranny is dated correct at C5AP 7006A
Pass side Exhaust man is correct at C5SE9430C
Intake is correct at C5AE425C
But, the following are where I am confused:
Block has a code of C6ME-A - also has the letter E on one side by itself.
Heads are C8AE-H (but many of the parts inside heads have date code of C4AE)
Driver side Exhaust man has D2TE9431AA
Main Bearings have date stamp of C2AE
Pistons have stamp of C6AE
There is also a stamp of the number 30 and the number 6, both on the first lobe of the crank?? And a 2U on the 3rd lobe.
I am going to try and attach some pictures, but I guess my question is this..... Is this common in the late 60s, or is this just a rebuilt motor that has been thrown together with random parts? And, does the 2U, 30 & the 6 on the crank signify anything special?
