I have a dodge project going. 5.9/auto. Rolled the dice on a rh46. Turned up snake eyes. Before I spend more on an od over a 904 or 727, just wondering what the impact would be on mgp. With a 5.9 selection it's going to be thirsty either way. So with other factors equal, anyone have hard numbers? Less rpms would be easier on the engine, but at 2000 to 3000 miles of driving a year, what's the return on od cost? Thanks
