Engines for Sale and
site has been designed,
not only to publicise our services to owners of vehicles powered by
the AC two litre, six cylinder engine but to provide a focus of interest
for the engines and indeed, for the cars themselves. These include:
All models of six cylinder Vintage &
PVT AC cars
Post-war AC cars such as the Two Litre
Saloon, Buckland Tourer, Ace, Aceca & Greyhound
Pre-war sports cars,
especially the GN and
Various pre- and post-war AC-engined
No substitute for experience
is a PVT engine rebuilt by us for a customer on the Continent, just one
of many vintage, PVT and post-war engines that we have overhauled for
our clients. In fact, we have probably restored to running order
more AC engines than any other concern, at least since the AC Factory
ceased to do so many years ago.
This has given us a rich store of
possibly unmatched experience with the proclivities and challenges
encountered with these sometimes idiosyncratic, highly individual but
rather wonderful engines.
There are others who rebuild AC engines
and supply spare parts but as far as is known we are the only company to
specialise solely in the AC engine.
Until fairly recently it was common
practice to replace a troublesome AC engine with one of another make,
the Triumph Six being a favourite while Bristol, Rover V8, Ford Zephyr
and even Alfa Sud units have been used. It even reached the point
whereby the value of a car was enhanced because it did not have a
troublesome AC engine for which few spares were available even if you
could find somebody prepared to undertake necessary repairs.
This regrettable situation has now
changed, even to the extent that owners of cars with 'foreign' engines
are replacing them with AC units. Cars with the right engines are
now becoming worth far more than those without.
We like to believe that we have been
largely responsible for this welcome trend.
Many of our customers have been kind
enough to write to us to express their satisfaction with the services
that we have provided, whether for engine overhauls or the supply of
sometimes urgently required spare parts. Their testimonials are
available for inspection.
Some customers have demonstrated their
confidence in our service and abilities with repeat business, one
gentleman ordering a third engine rebuild from us as part of his
programme of rehabilitating his fleet of ACs.
The first step
Whatever your particular need, the first
step is to give us a call so that we can discuss it with you. We
always do our best to help.

Logistic Support for the AC
'Logistics' is a much overused word
generally associated with lorries hurrying vast loads of consumer
goodies all over the country. In the context of the AC engine,
however, 'Logistic Support' simply means the provision of services that
enable the owner to keep his engine in good running order, namely:
We can supply the
majority of spare parts for the AC engine and, by reason of the huge
investment that we have made in spares, with the exception of some high
value, slow moving items we keep most items on the shelf. We do
not take huge deposits from customers for often mundane spares and then
keep them waiting for months while the parts are made.
Our first point
of reference for our manufacture of spare parts is the factory drawings
and, failing that, the use of original items as models. We adhere
as closely as possible to original designs and only incorporate
modifications where absolutely necessary or demonstrably beneficial.
We do NOT change things just for the sake of it or to ensure that the
part supplied will not fit an engine unless the customer purchases
another, perhaps even more expensive part.
We are constantly
adding items to our portfolio of engine spares and, as shown below, can
now supply from stock much-needed splined hubs for the PVT cars.
We are always pleased to hear suggestions
for the provision of further items.
This is an
important element of Logistic Support and we are renowned for our
promptness of despatch and, most importantly, for the care with which we
package our customers' purchases. Goods may be sent by post or by
courier and, where appropriate or requested, we will supply the carrier's
tracking number so that the customer can follow his purchase to its
Logistic Support is not confined to supplying spare parts but also
includes the rebuilding of complete engines, often from total mechanical
wrecks. In this context we not only support our private customers
but also several restoration companies who, perhaps unfamiliar with the
engine, recognise that using our specialist knowledge and experience is
preferable to climbing the steep and slippery AC learning curve
Our answer phone will be pleased
to take calls outside business hours. Visitors welcome but strictly
by appointment only.
note that we do not support or supply parts for the Bristol engine, the
Cobra range of cars or for AC-styled kit cars and replicas. Our speciality is the AC engine but in case of
difficulty, usually for customers abroad, we may sometimes source
mechanical parts other than engine components for AC-engined cars .
A widening range…
specialise in AC Weller engines we recently extended our portfolio to
include PVT axle hubs. With supplies about to run out and with no
possibility of small production runs for single vehicle orders, we
commissioned a substantial batch from specialist manufacturers, Orson
machined from high quality steel for front and rear axles, a set of
these hubs can transform the experience of driving your PVT car from one
of clonks and bonks and shuddering vibration into the smooth and silent
progress that should characterise these cars.
