A few questions on the aw450... I know the starter is rear facing on it, but is the block/bellhousing bolt pattern the same as the 4bd1/2T's??? I gather a bolt or two might not be in the right place due to the starter, but the rest? Giving up a bolt or two is not too much of a concern to me, if the other 8 or so work out.
I found a actual picture diagram of the aw450 internals. I dont have either a a440 or an aw450, but maybe someone can compare to the output on an a440...

does anyone know the gear ratios of the aw450? mostly concerned with OD ratio. Anyone with the Isuzu FSM have these availible?
The AW450 that came with the 4HE1 and 4HK1 engines will not bolt up to the 4BD1/2. I did try to mate up the AW450 bell housing to the back of a 4BD1 unsuccessfully as the back end of the blocks are different.
If you want more details on the AW450, you can download the FSM from here: Master Portal - forums.bauchan.org/Isuzu Manuals The AW450 is covered in the chassis manual, 1999 and later. Unfortunately, I couldn't find the gear ratios in the manual.
