Best Mopar engine of all time

The Best overall Mopar engine to me (stock) is the LA series 318.
The reasons are:
-Always just enough power in all body styles and light trucks to actually do the job.
-With proper maintainance, they will almost run forever.
-Decent gas mileage, and run on any low grade gas.
-Easy to get parts for. (And usually pretty cheap)
-Simple to work on.
-Mellow enough to cruise in but enough power to pass on the highway.
-Fits in all engine compartments easily.
-Responds well to minor performance mods without sacrificing reliability or driveability. (Dual exhaust for instance)

The only bad points are:
-Lousy factory timing chain and gears.
-The heat crossover under the intake manifold plugs up quickly.

Honorable mention goes to the slant 6, but it doesn't have enough power for the larger vehicles, especially on the hills or passing.
