Peter, two thoughts come to mind, "Lucas" is "Lucas" is "Lucas", the
fewer modifications you make the better-off you are, second is the
crankshaft not turning over, I just do not see a benefit in what you want
to do. If oil pressure at start-up was so vital they would have put it
there before now, there are some pretty hi-tech boys in Det. & Toyko &
Europe, I do not know of any factory made cars that have this, does
anyone care to explain why ?? I Know of hi performance race cars, but
that is something of a different engine.
