I need to get some information about doing an engine swap. My mustang has a straight 6, and I have another straight 6 that I will be swapping, but it has a lot more HP. Needed to find some info about doing this, I've heard it's a lot easier than changing it to a different type of engine, but a lot easier than what, really hard? I'm going need to do this before I install new exhaust on it.

What size engine do you have and what do you want to go to?
