Overfill the crankcase (10 quarts instead of five, for example) and remove the valve covers...high revving will foam the oil...it'll run/spray from everywhere...
Once the thing gets hot enough, you'll throw rods and start a nice oil fire from all the dripping/spraying/foaming.
Maybe a gallon of acetone in the gas tank will make it run that much hotter.
And stay far away from the thing if you're gonna do this stuff.
Be sure you use a pre-computer car with a carb and maybe just remove the butterfly altogether so you've got absolute WOT.
