98 mustang GT horsepower confusion

I am confused on what the actual horse power of my 98 mustang gt is. Wikepedia states that the 98 has 255 brake horsepower. But the 99 has 260 brake horsepower. So i am confused how a PI swap will be close to a 60 hp gain if there is only 5hp difference factory? Can someone pls explain this.

225 horsepower for the 98, not 255. That is slightly overrated as well. The PI heads also up the compression on the NPI engine, so that adds a little more horsepower over the 99+ cars stock ratings.

If it weren't for physics and law enforcement, I'd be unstoppable.
