I am getting a 97 F150 reg cab step side that has a 4.6 in it with 186,000 on it. I have a 99 5.4L long block in my garage that I was going to build a little. How big a deal is it to switch to a 5.4. I know it will bolt right in, but how about the wiring and all the tuning stuff? Is it all the same or not? Will probably end up with a big squirt on it too. BTW, it's a 4x4 too.

Thanks,

Kyle Jacob

Thanks, I did a search and that didn't come up.
