If you are thinking of using the 383/440 flywheel, think again. hemi's have 8 bolt flanges vs 6 bolt and use 1/2" bolts instead of 7/16.

unless your Hemi was built with a 440 crank,(someone would have to do this on purpose and it would create balance problems) the Hemi should have the 8 bolt flange. They will not interchange.
Here is a pic of the 383 bellhousing with Hemi Manifolds and Rob Mc starter.
The factory gear reduction or mini starter will not clear.
If you use the 10 1/2 inch aluminum bellhousing, set up as mentioned you will be able to use common starter and 70-71 Hemi Flywheel.
