Ron
Redpath Oldsmobile Special
This
special was built in the early 1950’s with its first
competitive event being in 1952. The car started off as a
full scale sketch on Ron’s father’s garage floor.
The car
consists of a space-frame chassis made from 2” cold drawn
seamless tube, one under and one over the back axle. Like
many specials of the time, Lancia Lambda suspension, brakes
and rear axle are utilized. The front brakes though have
been converted to hydraulic and the rear axle has a new
crown-wheel and pinion fitted to suite the V8 engine fitted
to the vehicle.
A Ford
side-valve V8 was the first power plant fitted driving
through a Lancia gear-box. Ford engines of various states of
tune were utilized over the next two years, the final being
a stroked Mercury unit running on alcohol.
Over
Christmas of 1954 a 5.3 litre Oldsmobile overhead valve
‘Rocket’ series V8 motor was fitted along with a Jaguar
close ratio gear-box. The engine was imported new from the
USA and considered ‘The’ engine of the time. It preceded the
small block Chev motor by several years and was of
over-square design and incorporated many of the features of
the small-block Chev engine. The engine was originally
fitted with a 4-barrel carburetor and coil ignition and
produced approximately 185hp@3800rpm.
Fuel
problems were experienced over the next couple race meetings
and it was at this stage that new inlet manifolds and two
twin-choke Holly carburetors were fitted. The coil ignition
was also changed for a Scintilla Magneto.
The car
was built specifically for Hillclimb and sprint meetings,
both these types of events being very popular in the 1950’s.
It competed at Rob Roy and Templestowe in Melbourne, Hepburn
Springs and Collingrove in South Australia, ascending these
hills at close to the then current records. Redpath’s best
year being 1955 when he came third in the Victorian
Hillclimb Championship.
The car
is now raced by Ron’s son Bill, who spent a number of years
restoring the car. Its first outing under Bill’s hands was
the Geelong Speed Trials in 1996; 40 years after his Father
competed at the first Speed Trials in 1956. Bill has since
competed at Rob Roy, Tarrengower, Arthur’s Seat, Mangalore
and Eddington sprints. |
