440 Dakota

Anybody have or doing one of these? Have a Dakota that just won't leave the driveway; found a B-body 8-3/4 and 440/727 combo for a good price. So,like I don't have enough projects (let alone getting any done), I thought this would be a good combo to add to the mix. Engine mounting would be elephant ears, trans crossmember tubular. Headers would be a big question: 1-3/4" 4 tube or a tri-y design? Would an A-body set of fenderwell headers fit? How about oil pan?
Regular rear sump truck or otherwise? If you've done this and have pictures to share, please do so! Thanks! Bob
