Wanted A Body A883 4 peed transmission

I am having a kiesler 5spd put into my 68 Barracuda right now. My car was originally a 318 Automatic car. When I bought it in '87 someone was trying to make a 68 Formula S clone out of it. So I bought it with a 340 and a A-833 in it. It has a 8 3/4 rear. It use to have drums all the way around, now it has disks on all 4. I was going to sell the 340 and A-833 as a package, to build a sweet motor. But I'm not sure what I want for a motor yet????
