Headers and a cam for low end torque. Dont expect alot of low end snot from a 302 but with the headers you should gain 20-25 hp and with the cam swap maybe another 10 hp. But choosing the correct cam for your needs is the secret. Dont waste your money on a chip for a 13 year old truck. I dont see how $200-300 plus dollars and 5-10 hp max is worth it, if they even make one for your truck. Do some simple bolt ons first and if that doesnt satisfy you, save you cash for a 351, 400, 428, 460 and then go pull some stumps!!
What gears does it have in it. If it has 3.55's you should consider a lower gear ratio. 3.90 or so depending on your tire size etc. If you provide more info on the truck I would be able to give a better answer. Making more power is good but if it isn't geared right the tranny will steal most of it from you. (Assuming an auto trans)
If an auto, I'd go with a shift kit. It won't give you horsepower, but you'll more efficiently use what you have. A chip would most likely be a waste of money, I don't think they help most stock engines much. With dual exhaust you could possibly lose some torque, you need some backpressure to a certain extent, but if you keep the pipe diameter around 2.5 iches it would help some. The headers would probably help though. Check out Steeda.com, I think they have a few parts for trucks. Other than that, expect to spend quite a bit- heads, intakes....
A diablo chip gives a 5.0 f-150 18HP and 26lbs tq..It also makes you shift points more aggrisive almost like a shift kit..A buddy of mine has this chip and it woke it up big time and increased his gas milage..For $225 you cant beat it.
i had that exact truck in a 4wd. they are a pooch to pull with. i agree with the guys that said r.v. or high torque camshaft- that will be a huge improvement. changing gear ratio is also effective but expensive if yours is 4wd. i'm a little leary on shift kits on e4od and aod transmissions if yours is the c-6 they are more durable and will take the added pressure better. i got so tired of barely holding 60 mph with my foot mashed through the firewall i finally got a bigger truck.... good luck
If I had the money I'd go with one of these kits from Edelbrock that has all matched components to take the guesswork out of it along with headers and dual exhaust to make it breathe. I really like their fuel injection kits for chevy's.
diff gears, cam, and a stage 2 shift kit (B&M) will make a ton of difference for you.... (if it's an AT, of course)... I had the same truck new... short box 2wd reg cab. I went to 3:91 rear gears, a 3000 rpm torque converter, and a crane cam ... think it was a 292?.... (lotta years ago...)
always match up cam, tranny & rear gears... you'll be happy & wont break a lotta stuff
