I think I bought it for GB pounds 600 (just $860).
It was a clubman’s racer Lotus 7. Like all the 7s it was very simple.
A spaceframe and monocoque combination with riveted aluminum over a steel spaceframe structure that weighed about 300 pounds was the chassis.
Power was by a Cosworth pushrod
Ford four-cylinder at 1558 cc displacement – the same displacement as the twin-cam Lotus
Cortina I owned immediately before this – and another exceptional car I wish I
could afford again!
Except, because the 7 was a genuine clubman’s race car, it was a dry-sump genuine Cosworth motor with two side-draft twin-choke 42DCOE Webers, ported head, header exhaust and a Cosworth RSC camshaft.

The cam was an 80-40-40-80 grind from a Cosworth SCA OHC engine
that was the de rigeur motor for Formula 2 open wheel racers back then. And we
are talking 1969. The camshaft overlap would see flame out of the exposed
carburetor inlets, sticking out of the left side of the hood.
The driveability
of the car was awful as it was way too cammy for the road use I intended. And
the fuel economy was ridiculous, so I switched out the camshaft for the
Formula 3 Cosworth RSA engine after a couple of weeks.
The RSA grind was way better for bigger displacements than the 1000 cc of Formula 3 back then, but it was still a monster. It was still so cammy it would break the Dunlop race drive tires loose in second gear as the revs came on to 5000. And in the close ratio Ford-Lotus gearbox from the Lotus Cortina racers of the day, that would be speeds in the 50s.

In the wet, it was a beast. The peaky camshaft would spin the
drive tires as it came on the cam in top gear – about 90 mph! Bear in mind the
car only weighed 1300 pounds. But it was the best handling car you can imagine. Set up with all kinds of negative camber on the 5.5-inch R6 shod front
wheels, it was neutral into a corner at neutral throttle.
So at a roundabout – there were and still are lots of them in the UK – entry on a trailing throttle would bring oversteer and a step out for the rear even though there were big Dunlop racing R6s on 7.5 inch rims. The oversteer would translate into opposite lock though a touch of steering through the apex of the roundabout and then power-out on opposite lock coming off the roundabout. The 7 was a hugely satisfying – and enormously forgiving – car to drive very fast.

The suspension was responsible for this: coil spring and
wishbone up front and an A frame to the base of the diff with coil-over shocks
at the rear giving a downward sloping roll center toward the rear. Just like
the ’65 Lotus Cortina I had so recently abandoned. That was an equally
incredibly balanced car that could be flung at corners, not just driven round.
The best thing is that it would always pick up the inside front wheel in a
corner to give a few more feet of road space through the apex of a corner!
But back to the 7, because it was a race car, it had no
lights and a straight exhaust on the passenger side exiting ahead of the rear
wheel. I fixed all that. Back then in the UK, there was no legal requirement for
headlamps (driving lights) so I fixed up marker lights front on the cycle
fenders and rear on the aluminum flares that replaced the original fiberglass
fenders so the lowered rear suspension had sufficient clearance.
That was part of the rewire I did when stripping and rebuilding the car, chroming the suspension, painting it a puce color instead of the Lotus green with yellow stripe. It had no ignition switch, either. You just flipped the switch for the ignition, the next toggle for the electric fuel pump, and then pressed the starter solenoid up under the dash.

The exhaust fix was easy. I just made up a can that looked
like a muffler and welded it around the straight-pipe exhaust. It looked legal,
but on a still night in rural Essex, a friend said he heard me coming from five
miles away.
Driving at night was a challenge with no headlights. At the
time I was working for Ford Motor Co, based at the Transit plant in
Southampton, but I’d spend weekends back in my home base in Wimbledon, South
London. So Sundays would find me heading back to the south coast on unlit
pre-motorway A-roads. The trick was to poodle along till something faster would
overtake, then tuck in behind till something faster came along and then tuck in
behind that.
One night the last to overtake was a spiritedly driven Honda
S800 – remember them – and I tucked in and followed like a limpet. Each time
he’d overtake, I’d hang back till the road was clear than blast up behind
again.
Eventually I ran out of gas. As a race car, the 7 only had a
4-gallon gas tank and no fuel gauge, but I always had a gallon can tucked
into a special location in the rear spaceframe. So I cruised to a stop and
pulled out the gas can. Meanwhile, the Honda stopped, then backed down to where
I was and the driver jumped out.
“I wondered what the hell that was,” he said, or words similar. “All I could see in the mirror were these two little lights dancing and bobbing around. Then I’d pass a car and the lights would disappear until there was a shattering roar and those lights would be in the mirror again.”

I drove that 7 everywhere. On evening, backing into a
parking slot in Montmartre, Paris, there was a bang from the rear and that was
that. The car had a steel, small diameter race clutch that was all or nothing, and in backing up, I had broken a half shaft in the Standard 10 rear axle (Yes:
Standard! It was a Triumph small car of the time and the axle Colin Chapman
chose for the 7).
I arranged shipment back to the UK and while I was waiting
for the 7 to appear at my doorstep in London I happened on a Standard 10
upended in a ditch while on a weekend in Sussex. It was the work of minutes to pull both
half-shafts from this wreck – fortunate, because only a month after replacing
the first broken half shaft, the other let go and I had a replacement ready to install!
Eventually I tired of the lack of heater, wind whistling in
through ill-fitting side curtains (there were no doors) and rain coming in from
every pore. So I built a beach buggy. Never mind there were no sandy beaches in
UK to drive upon. But I did take it to the Sahara Desert, and there’s a BIG
beach there! And that’s another story.
