Above is a short primer on NBC preparation. Also Marcella somewhere in prepper threads posted an really good explanation of EMP and the effects. Note effects usually hyped are worse than reality.
One might expect the 6.2 to have faded into history, but it hasn't: It remains an inordinately popular engine among enthusiasts, and survivalists in particular. The 6.2 is an entirely mechanical engine, with no electronics whatsoever. If the block is warm enough and the cranking speed high enough, the engine will fire and run, even after the black helicopters knock out civilian electronics with their electromagnetic-pulse machines. Gale Banks still catalogs the Sidewinder turbo system for the 6.2. Why? Because it still sells.
