You'll need all the intake stuff and a fuel pickup with an intank fuel pump from an EFI car for the fuel tank. Make sure you remove the low pressure mechanical inline pump unless the pump is on the block in which case it will still have to be removed. If you go with speed density just make sure the original computer is in the car (or at least a computer that is compatible with speed density). If you go with MAF you will have to get the MAF sensor, the wiring for it, and a computer for MAF. That's all I can think of for now.
