PostSubject: Need help. Your Suggestions on my 4.6 Liter.   Fri Jul 29, 2011 10:42 pm

Need help making more power from the 2005 F150 4.6 Liter 2 Valve Engine

Here is what WIKI says about it. 4.6 L V8 2004–2007 231 hp (172 kW) 293 lb·ft

4.6 LThe 4.6 L (4601 cc, 281 CID)[2] V8 has been offered in 2-valve SOHC, 3-valve SOHC, and 4-valve DOHC versions. The engines were also offered with both aluminum and cast iron blocks, depending on application. The 4.6 L's bore and stroke are nearly square at 90.2 mm (3.552 in) and 90 mm (3.543 in), respectively. Deck height for the 4.6 block is 227 mm (8.937 in) and connecting rod length is 150.7 mm (5.933 in) center to center, giving the 4.6 L a 1.67:1 rod to stroke ratio. Cylinder bore spacing measures 100 mm (3.937 in), which is common to all members of the Modular engine family. All Modular V8s, save for the new 5.0 L Coyote, utilize the same firing order as the Ford 5.0 L HO and 351 CID V8s (1-3-7-2-6-5-4-8). The 4.6 L engines have been assembled at Romeo Engine Plant, located in Romeo, MI, and at Windsor Engine Plant and Essex Engine Plant, both located in Windsor, Ontario.

2-valveThe first production Modular engine was the 4.6 L 2-valve SOHC V8 introduced in the 1991 Lincoln Town Car.

The 4.6 L 2V has been built at both Romeo Engine Plant and Windsor Engine Plant, and the plants have different designs for main bearings, heads (cam caps: individual caps per cam journal vs. interconnected cam "cages"), camshaft gears (press-on vs. bolt-on), valve covers (11 bolts vs. 13 bolts), crankshaft (6 bolts vs. 8 bolts), and cross bolt fasteners for main bearing caps.
