Your post is very hard to read, but the first part of it seems to apply to the Rover four or six cylinder motor.

Overhead inlet/side exhaust engines had a period of popularity from the thirties to the sixties, after being popular in the Edwardian period. They were used most notably by Rolls Royce, Rover and Willys-Jeep. As far as I am aware this design was never used by Leyland, although the Rover engines continued in production after the company was sold to Leyland.

Taking the Rover engine, originally designed in the thirties, it did not get into production until after the war. The valve layout allowed two significant advantages - it was an elegant way of constructing a hemispherical combustion chamber with cross flow, and given the need to use a long stroke engine for tax reasons, allowed a much larger intake valve than could be accommodated in a two valve head.

As is still the custom, as a general rule servicing and repair costs were ignored, although remember that the engines were originally designed for the upper middle class market, and also that labour was a lot cheaper in the thirties. Compare for example the Td5 head that cannot be resurfaced but must be replaced - and not cheap.

Used on Chev. Corvette long before that.

Please use some sort of punctuation and spacing, I have no idea what your on about.

As far as Fibre optics, My Grandfather had a fibre optic map light in his HR holden which he bought in 1969, the light not the car.

I was always amazed as a kid that such a small pin head light could light up the whole front seat at night.

We had one of those fibre optic lamps in the 70s.

I still have a lava lamp.

I loved the 70s, though I was just a kid so couldn't make the most of it.

Yeah, I was born in 72 but the best part was that in the 70's in the country town I grew up in, we could have breakfast and disappear for the day and come back at dinner and we were safe.

It's getting rarer and rarer for kids to do that these days and I get nervous when my kids go to the park which is nearly across the road from our place as you just dont know anyone in the street anymore in the city, we kind of know the neibours each side and over the back of us but none of the others even say hello if you give them a gday when you pass them while walking down the street.
