Re: neg Battery Cable location
The starter is the main current load. As long as the ground cable is connected to the block such that the starter can pull a few hundred amps through it without a voltage drop you'll be fine. As for ground straps, those are primarily noise suppression devices although they also provide a return path for the oil pressure and temp sensors that are grounded to the block. The main body ground is a pig tail lead from the battery (-) to the right fender just below the hood channel.
