would it not be cheaper to just get the motor and build it to your specs and get the heads? Just trying to think of the most cost efficient way of doing this.
I know I could but I am going for something one off and original. I have had the truck since it was brand new and my grandpa bought it for me before I was even old enough to drive. It has lots and lots of sentimental value to me as he is probably the biggest influence in my life and wont be around for much longer. He's 88 and a retired wwII fighter pilot so his breed is very limited. So the truck is not going anywhere I will always have it. My uncle has plenty of fast cars that I have access to whenever so it's not about that. Its about doing something that hasn't been done before and something different.
( And justin if things go as they are supposed to then who says I can't have the truck and a fast car A man can never have too many toys haha)
I think you did the right thing. The GT500's motor is WAY ahead of the 3V truck motors. Yeah you can build the truck motor with good parts, but it is a lot easier to start with something already intended for such service. Some here need to do a lot more research on what goes into these motors and what they are capable of.
I'd do the swap then talk to Evolution about a twin 67mm kit...
ok guys, I'll try and remember to get the article from work tommorow.... I spoke about this before.... in a ford truck mag, they built a hi and low comp 5.4 4v motor, took hp readings, then slapped a blower on it to see the results of boost on the diff motors to see the results of high comp vs low.... with a built short block, ported 4v navigator heads, and the cams they were running they pulled 1,032 hp on the low comp and 1300+ on the high comp motor!! for way under 10K then all you'd have to do is get the navigator harness and swap it over. Run all the same accesories.
some of you may have the mag... it talked about the Roush F150, and the saleen f150 It's not but 8 months old I think

Already talked to Fred at Evolution and Justin at VMP. Looks like the TVS is the way I'm going to go. How does 650-700rwhp sound?
Navigator heads and GT500 heads are NOT the same. What people fail to realize is that the GT500 engine is a "built" engine with ported and polished heads with high performance cams.... from the factory!

In 1999, Ford introduced the DOHC 4-valve 5.4 L in the Lincoln Navigator under the InTech moniker, making it the second engine to use this name. Ford later used versions of the DOHC 4-valve 5.4 L in the 2000 Ford Mustang SVT Cobra R, the Ford GT sports car, and the Ford Shelby GT500. The DOHC 4-valve 5.4 L is also used in the Ford Falcon line in Australia under the Boss moniker.
The SVT Cobra R version of the 5.4 L 4-valve V8 had several key differences from its Lincoln counterpart. While the iron block and forged steel crankshaft were sourced directly from the InTech 5.4 L, the Cobra R powerplant benefited from new, high-flow cylinder heads that were designed with features developed for Ford's "Rough Rider" off-road racing program, application specific camshafts with higher lift and more duration than other Modular cams, forged I-beam connecting rods sourced from Carillo, forged pistons that provided a 9.6:1 compression ratio, and a unique high-flow "cross-ram" style aluminum intake manifold. The Cobra R was rated at 385 hp (287 kW) and 385 lb·ft (522 N·m) though chassis dynamometer results have shown these ratings to be conservative with unmodified Cobra Rs often producing nearly 380 hp (280 kW) at the rear wheels.
The Ford GT version of the 5.4 L is a highly-specialized version of the Modular engine. It is an all-aluminum, dry-sump 5.4 L 4-valve DOHC with a Lysholm screw-type supercharger and showcases numerous technological features, such as dual fuel injectors per cylinder and oil squirters for the piston skirts, not found in other Ford Modular engines. The GT 5.4 L benefits from an improved version of the high-flow 2000 Cobra R cylinder head and unique high-lift camshafts. The GT is rated at 550 hp (410 kW) and 500 ft·lbf (678 N·m), though independent tests conducted on chassis dynamometers have shown these numbers to be conservative, with as delivered Ford GTs often producing nearly 550 hp (410 kW) at the rear wheels.
5.4 L 4-valve DOHC supercharged V8 installed in a 2007 Ford Shelby GT500
The Shelby GT500 uses an iron block 4-valve DOHC 5.4 L with an Eaton M122H Roots type supercharger and air-to-liquid intercooler.[10] The GT500 5.4 L shares its high-flow cylinder head castings with the Ford GT, with only minor machining differences, and shares camshafts with the 2003–2004 Ford Mustang SVT Cobra; which have less lift and duration than the Ford GT camshafts. All of the 5.4 L 4-valve engines destined for use in SVT vehicles, such as the Ford GT and Shelby GT500, have been hand-built by technicians at Ford's Romeo, Michigan plant.[6]

Being one off and original is cool. Untill something breaks. Like a driveshaft. Or the pump in your built tranny. Or your Torque Converter. Or some one steals your truck because its so cool. Or you suck up water on the way home from NC. All things that have happened to me this year. I haven't had a dependable truck since I had the engine work and bumped up the boost. These trucks weren't made for this and once you get about 600 crank hp **** starts breaking all over the place.
Worth the money and time? Only when someone tells you your truck is bad azz or you smoke some one on the road or at the track. Other than that you have a truck that is only worth 14k with 20k worth of mods.
But hey. I do smile every time I drive by a group of people and they here my BOV.
