With respect John V6, why would one want to prevent the beneficial effects of vacuum? I am very curious

On another unconnected note, I am Canadian and therefore have no patriotic urge to buy locally, aside from using the many machine shops unbridled by many legal liabilities and insurance regulations. Vast sparsely populated primary economies cannot afford such niceties. Though I buy most of my Morgan parts in the UK of course, my PRIMARY rule is to buy the most suited components for my hobby car, irrespective of cost from any place that produces them. Italian rad fans (SPAL), Mulberry rads, British engine blocks, and some American (the king of the world automobile aftermarket, safety thermostats, wiring products and so on. The smartest radiator caps are from the USA. I am an unabashed fan of Brands Hatch, but being in the UK, they are not supplied with the world's best rad caps, and certainly not Melvyn.
