Identifying your 4.2L engine
Ok, this is what I found out in case anyone is interested.
There are two main codes on a block that can help identify a 4.2L engine
1st. ENGINE DAY BUILD CODE. This is located on the passenger side of the
block just below and between #3 and #2 spark plugs holes. It's a flat plate
and has this format:
The Engine Day Build Code consists of six characters:
1. Year built code
2 & 3. Number of the month
4. Engine size/type code
5 & 6. Day built
Mine is 012C05
Which comes out to:
0=1980 or 1990
12=Dec
C=2v carb
05=day of the month built
See this site for more info:
http://home.att.net/~farna/amtech/amcengcodes.htm
I was unclear on whether this would be a 1980 or 1990 engine. To narrow
it down I located the Engine Serial number (2nd main code) which is located
right behind the O2 Sensor on the Drivers side of the block.
Mine reads: EF3235444
When I looked for this number on remanufactured engine sites I see that
this block serial number started in 1981 through 1990.
Therefore the best determination I can make is this engine is a 1990 made
engine.
Hope this helps someone.

Re: Identifying your 4.2L engine
Umm... Bill yours is a 76-89 258 2bbl carb engine....
That is what the 'C' means.
The '0' means 1980.

Re: Identifying your 4.2L engine
Cannot be. The block casting "444" was not used in 1980. C does stand for
carb though.
