At this point the next step would be start trimming the extended bell housing. I tried to come up with a good reference point to take a measurement from and ended up using the centerline between the 2 oil holes that are seen when the oil filter housing is removed. My adaptor plate on the non-extended block is 1 1/8" so from the center line for a total thickness of 2 1/2" from the measuring point. I would recommend that you stop cutting at about 3" to 3 1/4" (maybe a little more if your using the thicker flywheel) so you can gradually cut to the correct depth. The key is to cut the depth so that the bellhousing positions the starter drive gear into the proper depth on the ring gear as explained in part 3.
