5.4 Triton Engine shop
I know ive poted before but im hoping maybe somebody knows this time around. Im having problems with finding a engine shop that will work with my 99 5.4 triton v-8. Im in the littleton CO area. Im hopng to have the heads worked on, alng with the intake, and probly the block bored too. After thats all done, have the engine matched for a turbo charger. Possibly the turbo, does naybody know of a good shop in town that i can trust with my truck? lease let me know if you do, im hoping on getting the ball rolling on this one. ThanksS

What are your goals / intended use for the motor when this work is completed?
I ask because you may not need to have the head work / block bored or all the extras that go with these proceedures.
You mention your desire for a turbocharger installation. I suspect this is to help overcome the dreaded power losses that occur at higher elevations due to you Littleton, CO referance. From what I've understand a normally asperated engine will lose approximatily 4-5% of it's rated power for every 1,000 feet of elevation. This could be costing you as much as 50 hp when hitting the mountain passes in your area.
Any way, I recommend that you keep your motor in the truck in your search for power, if that is what it is. The motor would have to be removed and totally disassembled to perform an over-bore requiring many new internal parts. (pistons, rings, etc.)
I further recommend that you look at one of the many supercharger installation options instead of the turbo route. The installation will be much easier as no modifactions to your exhaust system would be required. Note that there are two catagories of superchargers. They are the "Positive Displacement" and "Turbine" types.
The turbine is very much like a turbo with the exception of being driven by a belt instead of the engine exhaust. Think of a hair dryer, the boost pressure increases with engine speed and thus make most of their power in the mid to upper rpm ranges. For example, the current 5.4L makes it's peak 350 lb-ft of torque at 2500 rpm. Adding a turbine type supercharger and while the PEAK torque will go way up, it will be at a higher rpm. At 2500 rpm the increase will be minumal, maybe 20-30 lb-ft, while at 4,000 rpm this model may be up as much as 100 lb-ft. The increase in horse power generally follows the same track. (great for sports cars that don't require lots of low rpm grunt) In the real world 1,500-3,500 rpm range that most truck engines operate at you would only be just getting into the boost offered by this type.
The "positive displacement" type, be it "Roots", "Lyscolm", etc. The increases in power are experianced just off idle and increase from there. My current favorite as it is Torque that moves your 5,000 plus lb truck. Check out the Magnacharger or Kenne Bell web sites for more info.
Bottom line, save your over-bore for when the engine needs it after a major rebuild. I expect the performance after market will only get better for the Triton motors as time goes by, there are just too many of them out there for it not to.

One more item: your tires. I note that you want a lift kit and will likily put larger wheels/tires on as part of this. you may also make the switch to a numerically higher gear ratio so as to keep your motor in it's sweet spot, I think 4:10's at least
