[Tigers] All I have to do is learn how to type. "5s" & "6s" do look kind of alike.

[Larry Mayfield]

Yeah, I read that also. M however, lots without that letter.   I have 5
different blocks and today I am going to look and record every one of them
including the casting part number and date codes for block casting that I
can get to.  I am officially curious now.

                Some of the date codes Ford employed did contain a shift
designation but not the engine assembly date code.

 

Although it has not been totally confirmed that last letter in the assembly
date code is believed to be the Inspector's letter.

Wow,

Hard to imagine Ford having all those shifts....

I heard from a guy who does this kind of stuff for a living. He said the
last "C" in the date code is actually the shift that it was manufactured
(machined) during.  1st shift is A, 2nd is B, and 3rd is C.   So my guess is
that the block was cast a couple of weeks before machining, then on the
early morning if the 31st of March it was machined and made ready for
assembly.  He said the probability of fonding a matching date code down to
the shift was pretty slim.

Unless I'm completely misinformed, the final letter of the assembly date =
engineering level change,

Interesting date code you sent. What does that last "C" mean.. rest of it
says March 31st, 1966 [6=1966, C= March, 31is day of the month, last "C"
=?????]. Perhaps where it was machined?
