Yeah but unless you have a CV or GM you can't use it.
The transmissions are different. They have a long output shaft and tailshaft housing. Won't work on our cars either. Other than that they are internally the same. There is no difference in the engines at all from a civilian CV or from the same year (insert car here) with a 4.6
Unless you have a 99-00 Mustang GT that is. Those are better.

Yes--better cams, better heads and a better intake. It should add 40-50 hp or so once you get it tuned. But you'll need to make a few other changes too, like swapping over to the 96-97 Thunderbird fuel line from the filter forward.

The CV PI's EEC only increases shift pressures and slightly raises the shift points and speed limiter. When reprogrammed this doesn't matter since these will be changed making it just like any other CV performance program.
