can buy an old Rolls Royce/Bentley car in UK for about 5,000 British

keep the thing going.
Ask the Brits about that if you don't believe me.
I need to yank the circuit breakers and get back to working in my
attic.I need to remove a couple of junction boxes in my attic so I can
put down some plywood in those areas.

Studebaker had a flathead six in 1960. I know because there was one
in my 1960 Lark.

They would have been one of the last then as even Ford went OHV in
the mid fifties.

I got a deal on 5 1957 Plymouths in 1968 and had everything from a
baby hemi (332) to a flathead six. The Hemi (circa 1952) was gutless
and the flathead 6 was a monster chunk of iron. It did run quiet as
with all flatheads the valve noise was very minimal.

The flatheads had minimal reciprocating mass as valve gear, big
advantage but they couldn't take advantage of it as they couldn't rev
much anyway. Overhead valve with overhead cam is the way to go, even
twin cam.
Keep that reciprocating mass to a minimum for better get up and go.

Krypsis,
You are totally missing the point. I built my older cars when gas was 21
cents per gallon for pure speed and city cruising. My later cars have
just proven that I can make a car get better mileage than these half
assed cars being advertised now.
It *can* be done but nobody is even attempting it.
Now, please go work out the math for any piston engine and you will find
that over about 1,000 RPM for an 8 or 2,000 for a 4 is overkill.
Go see how much is lost moving those little Aluminium things up and down
100 times per second at 6,000 RPM.
Do your own math.
