Max,
All the above, plus. Without , what is called the Battery Temp. Sensor--which goes to the ECM the battery will not charge. The way I read it is; the Batt. Sensor reads the battery, sends the/a signal to the ECM, then the ECM turns on/off the alternator.
Yes, you will need both 02' sets, or four in all. Reads 'upstream and downstream' flow.

The fuel pump has to maintain AT LEAST 54 PSI AT ALL TIMES!
The GEN III uses hyperutectic pistons, different cam and of course the intake.

Be carefull on buying any EFI system, i.e.; ACCELL, HOLLEY, etc. remember these units were never set up for a 10 cylinder system. Just a side note for you, the Vipers use coils from one of their 6 cyl. engines and one from a 4 cyl. engine.

Wiring: It's easier to tell you what we did use rather than what we didn't. "ALL" engine controls, all transmission controls, minus the 'skip shift' lockout. Fan controls, batt. sensor, fuel pump harnes...this is a must as the ECM also runs the pump. What is a big plus using the Viper fuel system is that there is no need for a "return" fuel line.

Just some examples of what we deleted, basic electrical, headlights, etc., AC harness AND pump. (You can keep this though, if you're planning on running AC), Seat belts, anti-lock (brakes) system, theft, interior wiring for dash etc.

Think that should give you some idea, but absolutely check the book. Killing one system may effect another!
