Who has done a 5.7 with a833 4 speed Overdrive ?

A stock bellhousing will bolt up the the Hemi, minus one hole (top middle) that is missing on the Hemi block. So you just need to find an LA OD bellhousing.

Note that a conversion flywheel is still needed.
The small block OD bellhousing with the large retainer is an endangered species. lol I did find one in Oregon for $400 shipped.
