Default Driveshaft length and type

Anyone here know what length driveshaft I will need with a TH400 and a 12 bolt in my 78 grand Am? I will be running 1350 joints on both ends with a loop, is 3-1/2" steel the way to go or how about aluminum? Do I need 4"? What are some of you running? I know the longer the driveshaft the lower the suggested rpm, I imagine I will be spinning around 6000 max. Any help is appreciated. -Jim
