Why the new thread? You didn't like the one you started in the Eng & Trans section?

If you are looking for information you need to call it an A833 because that is what Chrysler called it. Some GM references use MY6. Also you are looking for an Overdrive version or A833 OD.
The trans held up very well behind 426 HEMI's so I don't think your 307 or a 350 is going to do much damage to it.
A search for A833 here on this forum will give results such as http://67-72chevytrucks.com/vboard/s....php?p=3895102
The hump situation mentioned only half applies to you. You have the bolt in hump, but wrong hole location.

Tha A833 OD has a 5 1/8" bearing retainer. Your SM465 has a 5 1/8" bellhousing and bearing retainer. When you read about turning down the A833 OD retainer, it is because they had a bellhousing for a smaller trans. The older SM420 4spd and the GM truck 3 spd's have smaller retainers.

Do you have a cast iron bellhousing with side mounts or the later rear trans mount?
