Upgrades for 5.0
Am looking for ways to get more power out of my 5.0. I use it for pulling a stock trailer so gas mileage doesn't matter. Was wondering about a chip or???? Also would like to know how to get better throttle response. Thanks Mike

I did the following to my 92 F150 302 4X4:
Mustang underdrive pulleys
Flowmaster 3" single exhaust cat-back kit
Bumped timing up 3 degrees from stock
Installed stock replacement K&N panel filter, removed baffles from lower part of stock airbox, and installed a stock air scoop from a 4.9 F150 (gets air from BEHIND the grille, creating a semi-ram air effect)
Set TPS to .980
Run one heat range COLDER Autolite spark plugs w/Motorsport plug wires
I never actually dynoed the truck after doing those mods, but when I bought it (with 158K miles on it and 235/75/15 tires), it only got 12-13mpg. It now has 221K miles on it, been lifted and runs 32/11.5/15 tires, and with the mods listed above it regularly pulls down 18-19mpg.
Hope the info helps you.

headers, high flow cat., cat back exhaust, take the pulley off of the air pump, chip, K&N fuel injection performance kit, electric fans, SUPERCHARGER.
i have all the following except chip, supercharger, electric fans. electric fans will be coming soon and eventually a supercharger.
you could even go to ford racing and get a crate 302 which i would love to have. If engine craps out will get this in a heart beat.
taking the pulley off of the air pump will actually give you a lot of power and not effect o2 sensor

well, timeing should help you out a lot.
as far as i'm told. underdrive pullys dont do much.
good exhaust. good plugs, and wires, and cap.
K&N filter, or some sort of K&N air mod.
Headers will work good too. 351 headers will fit on a 302. could go get some of those. =)
i dont know about the pully off the air pump.

There are lots of threads on this, please use the search function of the site. Power pulley's don't do much, I find it hard to believe you got 3mpg out of them when they make less then 5 hp relieve off the engine.
