I just did this, this is what you need to do. Use your old computer and fuel system, you will also need to re-use your fule rails, old coil packs and plug wires, you will need to use the old headers as well if you plan on running the mid pipe you have now. That is about all you need to worry about, but another thing is that on the 01 intake there is gonna be one Intake Sensor Connection, but on the 96-98 there is two. What you need to do is take the old connection off your old intake and plug it into the Drain Plug on the driver side of the block, then extend the wire from the plug and plug it in tere so your computer will get a reading of your temp, other then that it is very simple, all the mod motors run about the same, there are a few changes in the fuel and ignition system but that is about it, good luck.
