“The standard plates are designed to be slightly shorter than the block, so had to be skimmed to recreate the correct relationship.”
The mystery was solved.
Making sure every detail is right inside this Lotus
Like every other BRM, Stowe’s car was separated at birth from its original engine, which was replaced with an already fettled unit – in this case fitted with CPL 2 camshafts giving 130bhp – although later research showed that the exchange engine eventually found its way into another BRM.
With a competition-spec LAA block rather than standard LBA item, Stowe suspects it may have been left over from the 26R contract.
Other modifications included uprated inlet valves, at 1.55in rather than the factory 1.52in.
During the restoration, Stowe took the opportunity to replace the valve seats with hardened versions suited to running unleaded fuel.
Enjoying this rare, BRM-fettled Elan around its spiritual home
The bottom end was also given a refresh with new piston rings, rod bearings, main bearings and core plugs.
Though BRM offered its own steel con rods – price on application, rather ominously – Stowe’s car features standard C-type rods.
These were balanced and polished, along with the crankshaft and flywheel with the whole assembly double-doweled.
Fire up the feisty ‘four’ with a tickle of the throttle and the straight pipe clears its throat ready for a full-blooded assault on the hallowed asphalt surrounding British Racing Motors’ historic home of Bourne, Lincolnshire.
It very quickly becomes clear that this is no ordinary Elan.
The tuned Twin Cam really is a surprise package, somehow straddling the line between genuinely punchy performance over the factory motor while offering true usability.
‘The chorus of crackles and pops would seem obnoxious from anything else, but just feels right in the terrier-like Elan’
It’s perfectly suited to a car that has one foot in the paddock and the other in a public parking lot – docile enough around town, but leaping like a scalded cat on the open road.
It is a car that revels in being driven hard, too: the darty steering responds to even the slightest input, so throwing its minimal weight around and getting on the throttle early inspires much greater confidence.
Even without BRM’s pricey steel internals, the Twin Cam is safe to 7000rpm and it spins up eagerly.
Lift off and you’re rewarded with a chorus of crackles and pops from the exhaust that would seem obnoxious coming from anything else, but just feels right in the terrier-like Elan.
It is thought that just 10 Lotus Elan BRMs were ever built
Some BRM conversions were fitted with ultra-close gear ratios, but the standard four-speed transmission in this car feels perfectly matched for sprightly back-road performance, not to mention being a real pleasure to use.
It’s best to double-declutch, or take your time if you don’t, but the action is as sweet as anything to come out of the 1960s.
Only the servo-assisted brakes take a bit of getting used to, with a slightly unnerving hesitation to the pedal that tricks you into getting on them a bit too hard.
Pulling up after an afternoon’s spirited driving and finally cutting off the electrifying ‘twink’, you can’t help but feel as if you’ve been let into a wonderful secret, shared with just a handful of other people around the world.
Evocative and packed with history – and this Elan more than lives up to its prestigious breeding
That so few Elan BRMs were made ultimately comes down to Spence’s tragic death at Indianapolis in 1968, after which production ceased.
For those who didn’t mind getting their trousers oily – and many who bought Elans new did so in kit form to avoid Purchase Tax – the BRM modifications, though hugely successful, weren’t beyond being approximated at home.
And if you’re chasing performance today, you would get rather more change from an Elan Sprint.
Yet this car has a special appeal, from its purposeful stance to its playful nature.
Dripping with history, it’s a living, breathing link to the most glamorous period in motorsport.
It’s a car with all the effortless cool of Kate Eccles in the pits at Monza, or Jackie Stewart in his BRM P83 at Silverstone. As evocative as it is accomplished, this might just be the perfect Elan.
