Does anyone know how to ID an authentic XR cam?? Should there be a serial number stamped on it somewhere?

There will be a part number on it. Maybe ring up a Dealer and ask for the art number?

I rang a few places todaY too get an install quote on the cam (most were around $150) and this one guy reckons the cam wont run properly with the standard ECU... is this bullshit or what??
He reckons it will run lean... of course he was trying to sell me a UniChip....

I thought modified Falcons were prone to running rich not lean. This uses more fuel but is less likely to damage the engine. Still doesn't optimise power though.

The reason;

Lumpier Cam => lower manifold vacuum => the ECU thinks the engine is loaded more than it actually is => responds by dumping in more fuel.

Well if its any help, I ran a EF cam in MY ea and it ran like an absolute shitbox.

Yes it will run rich on a standard car but running extractors and 2 1/2 inch system it will actually run lean with a lumpyier cam.I expenced this with my car so I needed a chip and it went from 14:1 to 11.5:1 at WOT on the dyno and gained 8kw and nice pull all the way through the rev range.

It will run ok on a standard car.Remeber Brent, DaveG ran the same XR cam in his car without the chip and we didn't really notice any difference in performance.After the chip was done thats when it started to shine like mine did.I am not sure what AFA it was running but it would have been lean.
