Sounds pretty good, but wouldn't the sound be affected by the size of the engine too?

 

Also, where can I get engine kits to make it look better?

 

I have the 4.7L In my 04... Previous owner had a Flowmaster 40 (1 into two) ran out the back on 45's.... (nothing fancy, no tips, 2 1/4 piping not shiny)... Just plain exhaust... and mine sounds pretty good... Doesnt drone except at 65mph.... Easy fix, do 5 over or 5 under... Also putting it out on a 45 is a good way to make the guy at the light next to you crap his pants when u rev it to 6k!

 

Alright, cool cool. How much trouble is it to put a cam in weed? did you do it yourself?

 

That depends on how much mechanical knowledge you have... Have you ever torn down a motor before?

 

Sean makes a good point. The 4.7 is an overhead cam engine, so you'd be swapping two cams not one. AIRRAM does offer tools for loan for cam swaps, but for expertise you need at least the RAM manual, and a DF member if you aren't mechanically inclined. HO cams are probably the best bet for mpgs. Don't go hog wild on exhaust pipe diameter either. THe 4.7 does well with a 3 inch single, or 2.25 inch duals. Any bigger and exhaust velocity drops too much. If you cut the end of the pipe at an angle, that will reduce the strength of the reflected exhaust pulses, making things a little quieter. It also helps to extend the tailpipe a little past the bumper or side of the truck.
Weed hit on a good one--get an Efan. You can also perform some weight reduction... Centerline makes light 20 inch wheels if you truck has factory 20s.
If you really want to monitor fuel economy, get yourself a scangauge/AeroForce Interceptpr/MPGuino, or something that will display instant MPG or fuel flow. I think a Transgo shift kit might help...I didn't get mine for that, but it shortens shifts which should help a bit.

 

I have some mechanical knowledge. But the closest to tearing down an engine is a old ****** 4 banger which the pistons are rusted in the cylinder (which i am still trying to get tore down). So I haven't ever tore into a newer engine. So I would not say I qualify, I mean i am sure I could figure it out eventually. But I would definitely not feel comfortable doing it myself. But mechanics is the plan when it comes to college so. One day I could do it myself. lol. Also Shift kit is in the plans as well. It's going to be a slow process. Starting a new Job Monday (Dairy Queen) its better then nothing. And any money is good money when your in highschool. lol. So right now i am trying to get the money for my 50'000 mile tune up for Engine and Transmission. which is getting the Royal purple for both. K&N Oil filter. New spark plugs (which did yall say was the best spark plugs to go with?) should I go ahead and put a new air filter? Grease everything. I figured I should go ahead and change to ceramic brake pads. Good idea? New windshield wipers. I can use them. Should I go ahead and change fuel filter as well?

 

Also should I go ahead and put new radiator fluid?

 

Hey guys, im looking on LMC Truck and they have some throttle body spacers. It says it improves gas mileage and such. Would this be a good idea?
