Description

Fresh from a total nut-and-bolt restoration and in superb condition throughout; rare model, one of only 2,111 made; Sebring-style looks and colour-scheme

Initially fitted with a 68bhp 1500cc engine, the MGA was upgraded to 72bhp 1600cc spec in 1959 increasing top speed to 101mph. However, for the really committed driver, a high performance 108bhp Twin-Cam version was also made available from 1958.

Developed by Gerald Palmer using a modified B-Series engine with a twin-cam alloy head, it also featured uprated suspension, all-round disc brakes and exclusive peg drive wheels made by Dunlop (closely resembling those on the racing Jaguar D-Types).

Despite these mechanical refinements and 113mph performance, the Twin-Cam failed to sell in great numbers, due mainly to its high price. Only 2,111 cars were sold (1,788 Roadsters and 323 Coupes) before production came to an end in April 1960, the vast majority in LHD for the export market.

As the Heritage Certificate confirms, this MGA Twin-Cam Roadster was built in September 1958 finished in Ash Green with a Grey leather interior. As with most of the Twin-Cams, it was a LHD model destined for the North American market.

It was brought back to the UK in May 1990 by MG specialist Bob West, our vendor acquiring the car some years later and being the only recorded keeper from import, according to the V5C. Over the past seven years it has been treated to a total body-off restoration which has resulted in the magnificent example you see today.

The full extent of the work carried out is far too detailed to list in full here but is amply covered in many invoices on file. Coming from a dry State, the bodywork proved to be in remarkably good condition and needed little more than new inner and outer sills and a new boot floor. The chassis was equally good and was shot blasted and repainted in satin black, the body being repainted in the original Ash Green, all this work being carried out by Myddle Wood Garage of Shrewsbury at a cost over £8,500.

Like the green MGA Roadsters raced at Sebring in period, the car had no bumpers when it arrived from America so our vendor decided to keep it that way, fitting a new Sebring-style front valance which gives it a streamlined and sporting look. The vendor advises that all the original bumper mounting points are still present so it could be fitted with bumpers should the new owner prefer.

The engine was fully rebuilt, engineering by Hurley Engine Services of Bath who specialise in historic vehicle engineering. This included fitting a new set of fully forged high-compression pistons supplied by Arias Pistons of Billingshurst. New billet steel Kent camshafts were also fitted along with new bearings, reground crank etc.

Other mechanical goodies include a Derrington-style tubular 4-branch exhaust manifold, Bell stainless steel exhaust system, high torque starter motor, rebuilt SU carbs and a new wiring loom.

The gearbox was also fully rebuilt and as the original Twin-Cam clutch is no longer available, an MGB clutch was fitted with the flywheel modified to suit, the crank, flywheel and clutch all being properly balanced – something that was not possible in period and is believed to be one of the main reasons why these cars got a reputation for being mechanically fragile as vibrations tended to upset the solid-mounted SU carbs and cause fuel-frothing problems which could damage the pistons. Allied to the modern components and expertise employed in the engine rebuild, they should make this Twin-Cam far more durable than the way they originally left the factory.  

The brakes and suspension were all fully rebuilt as was the steering with a new right-hand drive steering rack fitted and a new RHD dash. The interior was fully retrimmed including new De-Luxe seats (hard to find and very comfortable) with Saville Grey leather seat covers and Flint Grey carpets all supplied by Mirror Trim of Bedfordshire. A new soft top was supplied by Moss of Manchester.

Since the restoration was completed the car has completed a few hundred shake-down miles and has recently had an oil change but the vendor advises that it should continue to be used fairly gently for another few hundred miles before the performance is exploited to the full.

As you can see in the photos, this rare MGA Twin-Cam is in wonderful condition throughout and has been starting promptly and running nicely as we have moved it around on site, with good 60psi oil pressure.

If the new owner has never driven a Twin-Cam they are in for a real treat and some very satisfying motoring lies ahead - the standard version just doesn't cut the mustard by comparison!
