is there any difference at all between a BOP th400 and a chevy th400 beseides the bellhousing shape? i found a rebuilt chevy th400 out of a 79' suburban (2wd) for $200, im going to get the trans adapter so it can bolt up to my olds motor... is there anything to expect? (are they built better, worse, etc.) below is the link to the posting for the trans... take a look

THANKS!

In addition to the bellhousing bolt pattern, TH400s come in three different tailhousing lenghts (not counting the 4x4 version). There are also bolt-on and slip on yoke designs and a number of different internal configurations as far as number of clutches, shift points, etc.
