The axle centerline to front of a "long" 930 bellhousing is about 9" (very close), and the input shaft is offset by 3" from (lower than) the output shaft centerlines (inverted application as shown in Chris' photo above). Add whatever the thickness of the adapter plate (I'm guessing 5/8" to 3/4"?) to get to the block. The shorter 930 will be about 1' less.
