Chris,
Seriously, here in Europe we have Shell V-Power (100 octane), or ARAL=20
Ultimate (102 octane). I usually fill up  with Shell V-Power at our filling=
=20
station round the corner. I recommend to use either Shell or ARAL all my=20
friends and customers.
=20
Btw. I have Dunlop and Avon crossply tyres on my 100 and 3000. I love=20
crossplys on Healeys, as they give a nice soft ride.
Here its not very pleasant to do long trips on motorways in a Healey, as=20
traffic is enormeous and lots of congestions and plenty of lorries.

Seriously?
What octane leaded fuel are you running in your engine?
100 octane 5 star leaded as per the owner=E2=80=99s manual?
A lot has changed in the last 60is  years mate.=20
Fuel octane. Lead in fuel.=20
Do you run your modern radials at the same pressures as 60 year old=20

    Thanks for that. I=E2=80=99ll certainly bear it in mind. Likewise, I=E2=
=80=99ll keep a
    close eye on my engine=E2=80=99s temperature. The latter is quite well
    protected with a modern rad, all the correct baffles, 5 blade fan plus
    electronic fan. But, as I said, I=E2=80=99ll keep an eye on it.

    Someone mentioned that he used =E2=80=9CIridium=E2=80=9D plugs from NGK=
. I googled
    them=E2=80=A6.horribly expensive. Can they be worth it in our old cars?

    For me, i prefer Champion plugs plugs to NGK, but that=C2=B4s a matter =
of
    taste. I think both, Champion and NGK, are of similar quality. Matter
    of taste, as I wrote. But NOT the car manufacturer determines the plug
    gap, its the plug manufacturer. Definitely the car manufacturer takes
    this for his specs in the workshop manual.
    There is to much hype about plugs anyway. I am working as a
    professional, Elecrtonics and Elecrtrcian engineer, at a big classic
    car parts supplier here in Europe and I never go away from the given
    plug gap as set by the plug manufacturer. Austin-Healey engines  are
    not high tech, they are tractor engines and can take a lot of misfit,
    but anyway BMC knew at the time what=C2=B4s best to do with them, even =
its
    printed 60 or 70 years ago.
    Some people try to adjust the fuel mixture with a CO-tester. You can do
    that, but it doesn=C2=B4t give best results for road use, especially in
    hotter climates and high above sea level.
    When you are very good in engine engineering and have all the tools you
    can try to find some more horsepower in your engine, but you always pay
    that with some more heat produced, which is not at all good for our old
    BMC engines.

    You may be right. Not sure.

    Actually I thought that the gap was determined by the car=E2=80=99s
    manufacturer ie one could expect to find the same plug in two different
    cars and to find that the recommended gap was not the same for each
    car.

    Likewise, the BMC manual suggests Champion plugs at 0.024=E2=80=9D to 0=
.026=E2=80=9D
    and that was some 60+ years ago. I=E2=80=99ve always been told that Cha=
mpion
    plugs aren=E2=80=99t the best in the world and I=E2=80=99m sure that a =
modern NGK can
    stand a little more heat than the Champions that were around 60 years
    ago.

    Anyhow, I=E2=80=99ll keep an eye on them. I=E2=80=99m a pretty tame dri=
ver so there
    won=E2=80=99t be undue stress under the bonnet.

    Spark plugs are designed and tested to be used with the gap given by
    the producer of the spark plug.
    When you widen the gap the plug gets hotter as it is designed for and
    the electrode can melt or wear very fast.
    Its a very short win you gain modifying them.
    I never understand why people think they are better engineers and know
    better than the designers of the system they use.

    I run my MkII BT7 on NGK BP6ES which were recommended by some of the
    wise ones on this list.

    The car has a =E2=80=9CSports=E2=80=9D coil and a 123Ignition distribut=
or. DW fast road
    cam=E2=80=A6etc

    Now, talking of =E2=80=9Crecommended=E2=80=9D, the rolling road guys to=
ld me to set the
    plugs at 0.028=E2=80=9D and pooh-poohed anything bigger when I suggeste=
d that
    I=E2=80=99d heard of much greater gaps with my approximate setup.

    So, I went with 0.028.

    The other day, I decided to experiment and set my spare set at 0.032=E2=
=80=9D.
    Same NGKs, no mileage on them..decent plugs. Anyhow, it made a very
    surprising difference. All round performance is much enhanced.

    Despite it=E2=80=99s 3:54 diff and 28% OD, it was never sluggish on our=
 local
    hills. But now it fairly zooms up them.

    To be frank, all a bit of a surprise.

    Not boasting=E2=80=A6just putting that out there in case anyone else is
    thinking of going up a few thou=E2=80=A6..

    When I asked about gaps a few years back, some of the suggestions were
    near 0.040=E2=80=9D. Surely that a bit much?

 some of the wise ones on this list.</span></p>
<p class=3D"MsoNormal" style=3D"mso-margin-top-alt: auto; mso-margin-bottom=

if; color: black;">Now, talking of &ldquo;recommended&rdquo;, the rolling r=
oad guys told me to set the plugs at 0.028&rdquo; and pooh-poohed anything =
bigger when I suggested that I&rsquo;d heard of much greater gaps with my a=
pproximate setup.</span></p>
<p class=3D"MsoNormal" style=3D"mso-margin-top-alt: auto; mso-margin-bottom=
-alt: auto;"><span style=3D"font-size: 9.0pt; font-family: 'Arial',sans-ser=

-alt: auto;"><span style=3D"font-size: 9.0pt; font-family: 'Arial',sans-ser=
if; color: black;">The other day, I decided to experiment and set my spare =
set at 0.032&rdquo;. Same NGKs, no mileage on them..decent plugs. Anyhow, i=
t made a very surprising difference. All round performance is much enhanced=
.</span></p>

uggish on our local hills. But now it fairly zooms up them.</span></p>

-alt: auto;"><span style=3D"font-size: 9.0pt; font-family: 'Arial',sans-ser=

anyone else is thinking of going up a few thou&hellip;..</span></p>
