The casting number 3214722 is for a '72-'79 232 engine. The stroke is 3.5". While this is a longer stroke than the 4.0L's 3.44", its not as long as the 258's 3.895" stroke. I wouldn't use it.
The casting numbers you are looking for are:
3214723, 1972-80, 12 counterweights, 66lb, 64mm nose
3235477, 1981-86, 4 counterweights, 46lb, 64mm nose
3727, 1987-90, 4 counterweights, 46lb, 54mm nose
The 4723 and 5477 will either require a spacer or have the nose cut for the pulley to fit.
