I know some of you guys like older motors so here's a really old one, and a really big one. A little over 7 litres (430 cu in)..... per cylinder and it gets hand-cranked! From what I can see they just tip the engine over top dead centre and then fire it from one cylinder. The test run starts from 1:40.
