The AMC 232 inline 6 (I6) uses a cast iron block and cylinder head
with hydraulic lifters, 7 main bearings, and a cast iron crank and
rods. It was the standard engine in CJs and Commandos from '72-'78 and
in '65-'70 J-series pickups and Wagoneers. While the engines for both
these applications have the same displacement, there are some
important differences.
Prior to 1971, the 232 had the "Rambler" bellhousing pattern, and
shared an engine block with AMCs 199 I6 engine. In 1971, AMC unified
their engine line by changing the bellhousing pattern on the I6s to be
the same as their V8s. At this time, the deck height and rod length
for the 232 was changed as well as the bellhousing pattern, and the
cylinder block was shared with the new 258 I6.
The 232 can be identified by the 4th character of the engine build
date code, stamped into the side of the engine block between and below
the number 2 and 3 spark plugs. Early (Rambler) 232s have a "K" or "L"
code (7.5:1 and 8.5:1 compression ratios respectively). Later (AMC)
232s have an "E" or an "F" (8.5:1 and 7.7:1 compression ratios
respectively). All other codes (A, B, C and M) are used for 258
engines.
