" 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.
