The engine has been completely rebuilt by Ralph Saunders (very well known Oxfordshire engine supremo) to fast road spec, which is equivalent to 123GT specification, which means around 100bhp.
The slight overbore was matched to an uprated camshaft, lightened flywheel and cam followers, and a ported and gas-flowed head to help it rev more easily, making it an utter joy to drive. It also has metal timing gears rather than the stock, more fragile, fibre gears, so long-term reliability is assured. The final bill came to well over £4,000 for the engine work alone.
The rebuilt twin SU HS6 carbs add a lovely induction rasp that is completely in keeping with a car that dismisses the odd hillclimb or rally with the same disdain as it does the supermarket run.
The Amazon runs very happily on unleaded as the valve seats were hardened when the engine was rebuilt and the oil has been changed every 3,500 miles with a decent 20w50 grade.
It’s hugely over-engineered and massively under-stressed: having a newly rebuilt engine of this quality under the bonnet is like asking Jack Bauer to take care of the rowdy kids outside your local off licence; completely unnecessary but hugely reassuring.
Rob Henchoz, who races and rallies Amazons, rebuilt the gearbox, which benefits from a competition overdrive (which cost a whopping £900 all by itself) as the standard Laycock de Normanville units are considered to be a little too fragile for modern use. She’ll now cruise at 85mph or more where conditions allow, so dicing with photocopier sales reps on the motorway network is effortless.
The springs and Bilstein dampers are all new, as are the original specification wheels. Which have had new Toyo tyres fitted to them, obviously. The final assembly and tuning was done by Amazon Cars in Suffolk.
The owner also reports that he’s fitted rear brake shoes and cylinders at the last MOT along with new track rod end ball joints; were he to keep the car he’d look to replace the front discs and pads and rebuild the calipers to cure the car of a slight pull under braking.
The gearbox and overdrive oil have also just been done and, as the owner himself so eloquently puts it: “The beauty of these cars is everything’s so easy to do - I could teach you how to service it before your coffee got cold.”
