That "Magic Fairy" has been bolted not only in the CJ's, but also in a lot of other of other OEM cars including Japanese, European and US cars, including GM.

For starters, you have a OHC engine with very efficient cylinder heads. Then add what is called in the automotive industry, Displacement on Demand (DoD) Systems.

The DoD technology enables the Engine Control Module (ECM) uses the information related to the operational status of the engine to implement real-time running efficiency of the engine and effects changes in the operation of the engine through the control systems that manage its operation.

I do not know if the these cars are using Variable Cam Timing (VCT) and/or Variable Valve Timing (VVT) like the new Ford 5.0 engine does. I have seen the ECM graphical displays for VCT and VVT and I can tell you you can program the cam events for maximum engine efficiency throughout the whole run.

If the next generation of CJ's have the new 5.0 engine, as proposed, with ECM controlled VCT and VVT, watch out.

I beg to differ. A naturally aspirate mod motor from ford (aside from the new 5.0) is best suited for use as a boat anchor. They are bloated, oversize, overweight (as big as a hemi), and don't run worth a crap without forced induction. Why do you think the "crate" CJ's are windsor base?

You are correct about the VVT/VCT, although DOD will have no affect on a race motor. If they are allowed to run VVT/VCT it will open a bigger can of worms than EFI did when it first came on the scene.
