Satte tenna i det sure eplet og gjorde et søk. Og vips fant jeg nok siden også du hadde vært inne på. Som du skrev var det mange små og store forskjeller. (Kromma eksostutt var den som gjør mest utslag spør du meg ![[Bilde: wink.gif]](http://www.offroad.no/forum/style_emoticons/<#EMO_DIR#>/wink.gif)
)
Så for dem som skulle interessere seg, her er lista. Nummerene kom hulter til bulter, gadd ikke å rette på dem...
Summary of HO engine feature differences:
(Compared to standard 4.7 liter engine)
1. Block - Detonation sensor bosses in the valley
10. Intake - low-restriction intake system (different resonator, air filter, air filter hose and housing)
2. Camshaft - custom profile lobes (designed for increased performance)
11. Knock sensors - two, stereo
3. Connecting rods - modified, with floating wrist pins (vs pressed-fit pins in standard V8)
12. Main bearings - tri-metal (vs bi-metal in standard V8, designed specifically for the HO engine)
4. Crankshaft - forged steel (vs cast iron in standard V8)
13. PCM calibration - unique programming
5. Crankshaft damper - unique to H.O.
14. Pistons - dome shaped for increased compression ratio
6. Cylinder heads - different shaped combustion chambers (for improved airflow). The letters "H.O." are cast on the front end of the heads.
15. Spark plugs - platinum tipped
7. Exhaust tip - chrome (2002 models only, decontented for 2003 models. Available only as a one-piece assembly with muffler)
16. Valves - unique exhaust valves (same lift as standard V8)
8. Fuel injectors - higher flow (+3.3 lb/hr)
17. Valve springs - upgraded valve springs (intake & exhaust. Larger diameter wire and more coils)
9. Intake manifold - modified (shorter runners)
