IMO the Taylor kit that comes with the aluminum box is about the nicest around.
You get Og cable that is really flexable. Screw on terminal ends for the positive cable so you can trim to the length you need an then install. And they are on TIGHT, yet can be removed.
Heavy duty hold downs.
And the box is awesome. Plus if you need to mount a cutoff you could add it right to the box. And then run the handle to the back of the car.
It would have to be a turn on/off, not a push/pull on/off, sinc the box isn't really sturdy.
It's the same kit GMHTP used on their silver LS1 drag car. (I got it before seeing it there

)
I run the ground to the body in back, and then run the positive through the car, an to the stock distribution block on the fender.
This leaves all the extra wires under the hood, and I do get hard starting. I think a larger wire from the block on the fender to the starter and a larger wire from the block on the fender to the alternater would solve the problem.
I may weight to do that though until I replace the battery with a Hawker lightweight battery.
