Bolts to bell housing no problem but you have to change the front frame engine mount brackets .BB uses different brackets. Also depending on the BB you are going to use you might have to use an aftermarket oil pan. Some pans don't clear the crossmember. There also can be problems with the tie rod ends hitting the pan. Check out Moroso # 20411http://www.moroso.com/catalog/categorydisplay.asp?catcode=11902. Don't let there catalog fool you the 20413 will NOT work on a 66. If you aren't using a Gen V/VI BB then call there tech support for the correct pan. Make sure you get one that is tapered up in the front like picture of the 20411.
Just doing this now too but with a 402...if you are going to run a performance oil pan you need one from Mildon to clear the crossmemeber...the only one that will fit trust me if you are not running stock. You'll need the bb engine stands and mounts that is unique to 65-67...after that they are all the same.
You can use the SB frame stands as long as you use the SB motor mounts with them.........the engine will sit in the exact same place as with BB stuff.....you just won't have the safety interlock feature that is part of the BB motor mount.
If you are running a manual tranny/SB clutch linkage the oil pressure sender on the back of the BB engine may interfere with the Z-bar. Creative plumbing or BB part will correct it.
