Top gear mph/1000rpm on a 403 etc.
What mph/1000 would I expect on a non o/d 403 (1953). I'm investigating one (LOY555. Anyone know it? It has not much history, the seller has bought a 400 apparently). I'm looking for a car to use & I take my present cars overseas quite often & a good cruising speed is essential. Also what is the 100A engine like on modern fuels...does it suffer from overheating/ vaporisation?
