On a kind of related note - while in high school in San Jose my friends and I would routinely cut class and stop at a local sub shop on our way to Santa Cruz. We'd order a meatball sub or some other hot meat sandwich, wrap it in aluminum foil and place it in the engine compartment near the intake manifold. By the time we got to the beach we had piping hot subs to eat. My Mustang with the 289 hipo heated things up perfectly. As an added benefit, I rerouted the window washer line to discharge at the dashboard near the center console, installed a fresh washer tank and filled it with vodka. With the flip of a switch, you got all you could drink while driving. Seemed brilliant at the time, not so much now.
