I believe that a 100 amp alternator is more than you will ever need unless you have one of those big ghetto boom boom stereos or something unusual that draws a lot of current. With regards to battery cables bigger is almost always better and it's hard to go over kill. One of the reasons I use welding cable, it is more flexible and easier to route,carries more amps and has lower resistance than a standard battery cable of the same size. I use the Ford style solenoid on the firewall or fenderwell, AWG 1/0 welding cable from battery to solenoid, solenoid to the starter, battery to the frame, frame to the engine. Also a good size ground from each cylinder head to the firewall. This is a trouble free system that will never have any hot start issues.
