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. Bill |

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. "Mike Romain" <romainm@sympatico.ca> wrote in message news:4038C045.67935D51@sympatico.ca... > Umm...
