Early, "non-smog" engine spec. dizzies
were carb. ported; "smog" engines were manifold ported, as I understand
from Lucas Distributor web sites.
Give Aldon your engine spec. and intended vehicle use along with octane
to be used and they will build you a
dizzy tailored for the same for less than
$300 and for an additional $75, they'll
do it with a PerTronix installed.
This "tuned" dizzy is actually part and
parcel of a "tuned" engine, though an
engine "builder/tuner" with a dyno will
do same for you of course, as he "dials
in" both fuel and ignition advance curves.
The Cooper "S" came with a 23 type
centrifugal distributor at a time when fuel
was relatively cheap and emissions were
not a consideration except for rudimentary
PCVentilation.
As I understand it, the manufacturer's
thought was the Cooper "S" would be
ordered and driven by the enthusiast
who'd most likely be driving around with
his foot "in it" most of the time; referred
to as "spirited" as the English say!!
And, so it was!!
The last paragraph of your e-mail is very educational to me.
I always wondered about the ".014 to
.016" and why later timing "curves"
were given as "this degree to that degree"
as opposed to "earllier" timing curves
which were exact degree specific.
Thank you, Bill E.!
