I just did it on my stage car, Major pain in the a**. I am guessing you are using a Ford intercooler. I'd think twice about using it though, because there are very minimum gains from relocating the battery and it going to cost alot of money, and is going to add a major cost to that $$ saving intercooler. If your all set on doing this here's what you'll need from Summitt. 1 800 230 3030
Moroso cable kit part # mor-74055 $99.95
Moroso battery box part # mor-74050 $96.95
Flaming River battery disconnect- fla-fr1003-2 $78.95
On top of this, you will need to buy a battery tray and bolt or have it welded in, and buy or make brackets to kold it in, you will need to drill a hole somewhere in the rear of the car for the shutoff handle, and a bunch of fun wiring to meet NHRA rules if you are going to the track. "Good Times"
