Nope. Because the 3L was available easily when people started modding these cars, and especially because the turbo wasn't.
He's right, turboing a 3L with moderate boost will kill that engine. But then turboing that engine..... There is still some fun to be had there.

Please provide more info on this and/or link. The 4.0L SOHC V6 has never had VCT. Not for Explorer, Ranger, SportTrac or the new Mustang. A few prototypes engines were made w/ VCT internally at Ford but that's as far as it ever got. Now the 4.6L 3V V8 used in the new Mustang does have VCT.

Correction: It was the new 3V 4.6 and I found the article here:
http://www.fuelairspark.com/ArticlesAboutUs/Details.asp?ID=1027707949
"The variable cam timing on the Three-Valve motor is controlled by a pulse-width modulated signal from the factory computer. While we can control this using the SCT software on a stock ECU (on a chassis dyno), our FAST management system did not offer this capability. We had been running the testing with the cams in the default position (no electronic signal to the solenoid), and though we could not alter the timing electronically, we could adjust it mechanically.
To illustrate power gains (and losses) offered by retarding the cam timing, we retarded the cams 1 tooth. Changing the cam timing 1 tooth on the cam sprocket was the equivalent of 8.5 degrees (42 tooth sprocket/360 degrees). As expected, retarding the cams increased the power output above 5,200 RPM (to a peak of 369 HP), but dropped the power below that point (as much as 37 lb-ft at 3,000 RPM). The key point to remember from this test is by using the variable cam timing, we can have all the torque offered by the advanced position as well as the power offered by the retarded position."

Found some more info (and great pictures): Ford 3.5L Cyclone Info Having removed my MTX-75 once, the bolt pattern on the rear of the 3.5L looks very familiar: Who will be the first to attempt a transplant of one of these into a Contique?!

Nice!
Look, similar SVT style oil/water cooler. Waterpump is moved, that could be a problem. THe bell housing mounting area is more rounded though. Look at the rear mounted crank pickup sensor though. YUCK if that ever goes bad.
The basic block looks essentially the same design though. It might not mate to the transmission evenly, but it may go.

The big question is what would it take to make the crank fit a 3.0 block.

Humm... stroker... lol
Is it just me, or does it look like the 3.5 is a one piece block design?

Just you.  Actually it looks very similar to the regular 3.0 duratec. It looks similar enough that I wonder if a 3L/2.5L head bolt pattern and galleries are the same? I could see a 3.5L ovalport with correct waterpump drive, high compression without the valve shrouding in the 2.5L being quite the monster. I wonder what the valve sizes are for that thing anyway?

Who will be the first to try...??
Must be that jumbly-wumbly thing happening again.
