The Austin-Healey 100 is a true British sports car, all right, but there's something missing. What could it be? Yes, of course- a Vortec-supercharged 5.3 liter Jaguar V12, which is what Canadian lunatic Martin Jansen has installed in this '54. We don't get any horsepower figures for the engine (which seems odd, considering the engine builder goes by the moniker of "Dyno Dave"), but it's a safe assumption that it's much, much, much more than the 90 horsepower of the original A-H four-cylinder. The build quality here is just staggeringly good and the whole setup somehow fits neatly under the hood. We have no choice but to give this engine swap an extra heavy-duty Jalopnik Stamp-O-Approval™!
