Factory (OEM) CID for AMC Jeep 6 cyl is 232 or 258 AFAIK.

if it is an 86 then it should be a 258, also this could be a long block from Advance Auto IIRC they are manufactured in Mexico.

Only in America do you have the God given right to be loudly opinionated about something that you are completly ignorant of.

First, they really do exist. But not in a Jeep. Someone swapped it in.

The engine was used in AMC Hornets, Javelins, Concords, Pacers and Spirits. Knowing how the parts counters work with computers, try telling the guy the car is a 1982 Hornet or a Concord.

When you own a Jeep you learn that Jeep really stands for Just Employ Everybody's Parts. AMC outsourced everything. It's not uncommon to have a Ford ignition system and a GM Delco alternator, etc. Jeep owners have to lie to countermen all the time.

I'd rather be lost on the trails than found at home!

The 282 cu in (4.6 L) engine was produced by AMC's Mexican subsidiary Vehiculos Automotores Mexicanos (VAM) beginning in 1971 through 1986. This was similar to a 258 in stroke, cast with a larger 3.917 in (99.5 mm) bore, 0.16" larger than the 258, giving 281.7 cu in (4,616 cc).

Kudos to WindKnot & Davis77Cj - Good call!
