Just so people are clear: there are 2 different 232s. Early (with small bell and shorter stroke) and later (72 up with same bell as AMC V8s)
   There may be some '71 only longstrokes like the 258 with small bell.

" Also I know the 258's are the internal start to strokers, is the 232
" also? Was it a bore increase or stroke?

stroke. 199 - 3"; 232 - 3.5"; 258 - 3.895". all are 3.75" bore and
have the same pin height until '80.

290 and 304 slugs have similar dimensions.

4.0 is 3.875" bore x 3.414" stroke.

jeepspeed racers have used the 232 crank for a 'cheater stroker'; it
increases disp only a few cubes but bumps compression quite a bit.
i'm told the engines run 'very well'...

btw there are 2 rod lengths:
199, 4.0 - 6.125"
232 - 5.875" '64-'70, 6.125" '71-9
258 - 5.875"

block deck height was increased ~1/4" in '71.

290-360 rods are also 5.875", identical save for narrower big end.
