someone school me on my A833 for my swap Please

That sounds like the O/D version of the 833.The over drive 833's had the larger bearing retainer and you'll need to find a over drive bell housing to be able to use it. I have a o/d set up, I found the bell housing at Carlisle a few years back. Is yours a cast iron main case or aluminum? Cast iron is the better set up. The bell housing should bolt up to your 360 motor with no problem. Make sure you have the correct 130 tooth 360 flywheel, it is balanced differently then a 318/340 steel crank.
