Re: Identifying your 4.2L engine
 

I stand corrected. C does not stand for carb and it does say the dates run
to 89.

C- 258 2 bbl (4.2L, 76-89)

However, every site I've looked at similar to this one:

http://remanufactured.com/AMC_Jeep_Engines.htm

says that the serial number of 3235444 started in 81, not 80 which is why
it's confusing.

Go to this site http://remanufactured.com/AMC_Jeep_Engines.htm and search
for 3235444 and you'll see what I mean.

Re: Identifying your 4.2L engine
 

They warned about that on the first link Bill.

Some of the numbers went on when it was made and some went on for the
actual model year it was sold as or built for.

Here is a quote:

An important thing to remember about AMC engines is that changes were
made on a calendar year basis, not model year. The engine plant ran on
its own schedule! This is why some 1980 model vehicles have the "heavy"
258 and others the "light" 258 -- changes were made early in calendar
year 1980.

Re: Identifying your 4.2L engine
 

They warned about that on the first link Bill.

Some of the numbers went on when it was made and some went on for the
actual model year it was sold as or built for.

Here is a quote:

An important thing to remember about AMC engines is that changes were
made on a calendar year basis, not model year. The engine plant ran on
its own schedule! This is why some 1980 model vehicles have the "heavy"
258 and others the "light" 258 -- changes were made early in calendar
year 1980.

Do you have a plastic valve cover?
