fuel tanks residing in the boot are a neat
touch, another example of Ross thinking
things through and coming up with a
clever solution.
Despite much of the bodywork already
having been fabricated, Ross had still yet
to tackle the bonnet, don’t forget the
engine bay is 2.5 inch shallower than
standard here! “I modified the bonnet to
fit over the engine, but once I’d fitted the
twin SU carbs it wouldn’t close over the
dash pots so I made two small tear drops
to give them clearance,” Ross points out.
Luckily, this guy isn’t put off by these
small problems that suddenly arise! And
another tricky situation followed as the
next task was to cut and fit the glass. “It
took three windscreens before I finally
got the one I was happy with,” Ross
laughs, “the rear screen was also tricky

originally from an Austin 1300GT and
needed a proper strip down and rebuild.”
A +20 thou overbore takes the A-series
up to 1293cc and it now benefits from a
286 Kent cam, hi-lift rockers and twin
1.5 inch SU carbs. The standard 1300GT
remote gearbox remains but Ross has
also added a four cross pin diff,
lightened and balanced f lywheel, Hardy
Spicer output shaft and rally driveshafts.

TOO BLUE
“It’s a gentle upgrade rather than full
custom, but the overall package is
certainly lively enough,” Ross smiles.
The alloy radiator and overf low tank
along with the blue silicon hoses help to
brighten up the bay, while the Manif low
manifold and twin box side exit exhaust
sounds the nuts too. The cut down twin

widening and reshaping in order to sit
correctly on the modified shell.
Attention then turned to the chassis in
order to achieve that perfect stance. Both
subframes remain standard, and alloy
Superfins and adjustable radius arm
brackets have been added to the rear.
The suspension itself centres around
Spax lowered shocks with modified
suspension mounts all round, along with
red dot cones and Hi-Los. Adjustable
bottom arms and tie bars have also been
added, while polybushes help provide a
more reassuring drive. Those larger
diameter wheels also provide room for
bigger front brakes, something Ross has
taken full advantage of with four-pot
calipers with vented and grooved discs.
“The engine was already in the car
when I bought it,” Ross explains, “it was

Late six-clock dash has been
repsprayed metallic blue.
