Outdoor wood boiler

Lol . .

Engine on the run stand there. Just for the fun of it I wonder how much heat you could make with that V8 running outside then plumb the coolant to the inside the building to a radiator with a fan on it for heating.

Burn a little gas, but oh well. If you have a 10:1 cr engine that will make heat sitting there running.

Hence the Outdoor Boiler . . .

Well you should run the engine IN the shop. They radiate a fair amount of heat right off the block/ heads LOL
