I'm looking for a older dodge around 1998 or so, which would give me a choose on 12 or 24 valve. Anyone happen to know which is better and what rear end would be best? Not really looking for power but like the sound of the engine and would like to get the best mileage. I now have a 1996 Ford with power stroke and like that but engine about dead so want to switch over to Dodge. Thanks Curt
