ok first you need the fox double sump oil pan ..and v8 moter mounts...are you runing a carb or fuel injection if a carb than u need to remove the fuel pump from the tank and run new feul lines all the way  back  also run a ruber line in the pick up hanger where the pump use to be to the botom of the tank  now you need a in line pump i use the holly pump ...very good pump ...mount it  in front of the rear end at the tank works great ...i also had to run a wire to my alt becuse i ran the original v belt set up ...but that is going to change here soon with the serp conversion ....also the auto tranny sucks ...you need the 5 speed ...unless you are going fuelinjected if so than i cant help you with all the details...good luck ..any mor qust just ask
