re: OB motorheads- will supercharging a 6.0L V8 gas engine

thanks for all the info. I ask b/c my employer is moving towards all gas engines in the 3/4 ton company trucks. this has caused some unhappy drivers who want to stay with diesel. company believes operating costs will be lower with the gas engines.
That aside, the debate over the decision degenerated (as most debates usually do) into a pissing contest amongst the group about superchargers and fuel econlmy. thus my inquiry.
