I started looking into this, as parts are available to bolt to an NV4500, and this is a modular motor pattern. The ECM has not been officially released, but it will be soon. I can’t figure out how high the motor sits with the intake. Any info out there?

One article about it says "those w IU th big engine bays.....". I would say that eliminates Jeep CJ's. Might fit, the cooling system would probably be another story.

I did’t realize this board was sponsored by Fox News, but if anyone has any exterior dimensional information on this motor, that would be great. The width seems possible, but I can’t find any information on the height.

Sorry to say it like that. Just that every person that try's to change out original is left in an almost impossible situation to change it. So an engine like that sounds almost impossible. Like I said, Sorry

I think it would be a cool swap. The 7.3 has an in block cam which would reduce the overall width and deck height. In stock form that engine makes more power than I would feel comfortable running in a scrambler sized vehicle. It is something different and cool and you would likely be the only person with that setup.

Before starting I would ensure that you will be able to smog it in CA. The reason jeepers and motor heads dump on CA is due to the difficulty of getting seemingly minor changes approved. There are shops that specialize in smog approved upgrades, its just harder there than in other states.

Being that the Godzilla is available as a crate engine, I’ll bet they get a version that is CARB approved, much like some of the LS performance engines from GM.

Regarding power, it is in line with many of the LS engines and Hemi’s. Sub 500 hp and tq does not sound crazy in a scrambler.

I think this would be a neat alternative to the “LS swap it craze”. (Coming from somebody working on an LS swap).

I was going to install a free 1998 Explorer 5.0
Small block, and still might, but with the the P heads causing problems with header availability and the computer issues and fading interest in, “reflashing,” the original units, it might be more cost efficient to move on to newer technology. The Godzilla is far more narrow than the SOHC modular motors but the height might make it impossible.

Thanks for the good info, and I appreciate the apology (I would rather avoid politics and California bashing on the auto forums). I am going to keep researching this. I will email Ford about the ECM and see what they say. My original plan was to use the Explorer motor and find a used supercharger, but with the parts needed to mate Explorer and Mustang parts and then fit them in the CJ it might work out easier and not that much more expensive to go another route.

What about a mod motor ZF instead of the NV? Less "custom" parts, assuming it all plays well in the pilot bearing area.

Ford Performance says packaged dimensions of the crate motor are:
Packaged Dimensions = 36.5" x 44.5" x 36
Packaged Weight = 737 lb(s)

ZFs are typically larger than the transmissions with a separate bell housing. I already have the NV4500, but I will have to make sure that the parts will all get along.

Concerning Smog, not all zip codes in California require an inspection, FYI. I’m still annoyed with the end of the, “rolling exemption.”
