What transmission is it hooked to 4l60e or 4l80e? A few suggestions if I may? If you are trying to make it look "good" under the hood, the best way is to tuck the brain box and the wiring under the dash behind the glovebox (which should be easy as you've taken out the heater stuff) The only downside with that is some wires need to be extended which sucks. Mine still runs to the drivers side front of the fender, kinda messey looking but functional. my other suggestion, ride that bish til the wheels fall off! Its a great engine to have, and gives you plenty of power while taking the abuse!
