Bell Housings
The bell housing bolt pattern for the old AMC 196 Straight-6 engine is the same as for the more modern early 199 and 232 (used in 1964–1971), but the 196 had different dowel pin sizes. The AMC GEN-1 V8 used a different bell housing bolt pattern that was larger in diameter than the six cylinder bell. When AMC dropped the GEN-1 V8 engines after 1966, the bell housing changed, but all 1967 and later GEN-2 and 3 V8 bell housing bolt patterns are the same (including late 1966 290 V8s). The bell housing for six-cylinder engines changed to match the V8 in 1972 when AMC switched from Borg-Warner to Chrysler transmissions automatic. The flywheel also changed from 153 teeth (a common Chevy size) to 164 teeth (a common Ford size).
The Iron Duke I4 used by AMC in Jeeps from 1980-83 used the standard small block Chevrolet bolt pattern bell housing. The later (1984-02) AMC I4 had the GM 60 degree V6/I4 bolt pattern, and this was retained for the life of the engine. AMC often used lighter duty transmissions with the four cylinder engines.

Famous quotes containing the word bell:
“Those feelings of envy are familiar to many of us. We see our children accomplishing things that we’ve always been afraid to try, or we give them opportunities that we never had, and we find ourselves feeling jealousy mixed with our pride, or we feel resentful when they take it all for granted.”
—Ruth Davidson Bell (20th century)
