For exhaustive recipes for cooking in the engine compartment,
check out a book entitled "Manifold Destiny" found in the cooking
section of your FLBS.

That's an interesting idea.  Long ago when I was young we used
to cook hot
dogs and other items during sports car rallys, but it never occured

to use the van.  We used to put the food on the exhaust manifold -
where
would you put it on an air cooled Westy?
