5.4 performance in a truck

[Coupe Devil]

Hey guys, I post mainly in the Windsor Fourm and Blue Oval. I have a buddy that has a 1997 F-150 Off-road. It has the 5.4 and auto. It has a 6 inch suspension lift and 3 inch body lift. It is all stok other than that and thw wheels and tires. It is also settin on 38x 14.50 swampers. He wants to add more power obviosly. I told him, chip, headers, pulleys. He asked me about an intake spacer also. Since I dont deal with new 5.4's I dont knopw if its worth the money. He also will be adding a super charger in the next year. He has a "True- Speed" box to correct the tranny shift points form the lift and a K&N also. What do you guys suggest we do for more power until he can get the super charger. He isnt concerned about mileage (i.e. the 38 swampers) but has about $800 to spend right away.

Thanks
Brad
