who is the manufacture of the 833

Yes, they were built by New Process. Funny name though. You can learn everything about them on BigBlockDart.com Something you might want to look into is a factory setup for hydraulic actuated clutch. My '95 Dakota Magnum V-6 has that set up with the 5-speed. If you could find one in a bone yard, you could scrounge the bellhousing (fits all smallblocks), the clutch outfit, throwout fork & bearing, hydraulic slave and the clutch master cylinder. I haven't done this before but from looking at it, it sure does look feasible. Good luck. If you try it, let us all know about it, OK?
