you'll likely have to do away with the speed density system to see that horsepower. MAF, or back to carb.
you'll definitly be looking at a cam swap.

All you need to add to the trucks fuel system to run a carb is a fuel pressure regulator set to about 5.5 psi. Be sure to use a regulator the returns fuel to the tank so the pump stays cool. Then of course the adapter plate for the EFI manifold and the carb.
