I'm putting in the 454 BBC so I knew I'd need to make more room inside the engine compartment. So I moved my ABS box to where my ram air used to sit. Anyone who has a ram air through the hood or doesn't have a stock style air box can do this to give them more room around the headers. I just have to extend the 2 brake hoses (new ones from AutoZone) to the unit and two wires will need to be extended. I unhooked the other three brake line hoses and then bent the so that they would reconnect.
