Small block brackets, pullys, pan

i have a 72 340 bare block and heads going in a early A, timing mark on drivers side. Assuming small block pullys from around the same time are the same, preferably looking for a match set 2 grove crank, single grove water pullys and a alt bracket, do not need PS bracket or pully, but want a 2 grove crank pully Incase of aftermarket air. Also looking for a oil pan that will work in this swap and a distributor hold down, thanks
