If the Triumph Stag has a weakness it is its engine, which overheats whenever the ambient temperature reaches double-digits thanks to a cooling system that was borderline at best, even when new and properly maintained.
As a result, many owners chose to fit the ultra-reliable V8 engine from the Rover SD1 instead as a cost-effective 1980s and 90s alternative to constantly faffing about with the original, which is exactly what’s happened here. So, while the car’s engine is not original, the refreshed Rover V8 that now lurks under the bonnet has been fitted very neatly and offers almost unlimited cheap tuning potential.
Which can be a slippery slope, as the vendor will attest; there's an Offenhauser inlet manifold (with new gasket), a Holley 4160 carburettor (with unused rebuild kit), which add a few extra horsepower in addition to a very attractive induction rasp, an auditory treat that is underscored by the wonderful exhaust burble that emanates from the stainless steel exhaust.
However, being a cautious and methodical man, he also fitted a Stoney Racing electric cooling fan (properly wired in) and a new 4-core radiator, which he filled with the proper antifreeze coolant and deionized water! He went on to carry out a thorough service on the car, including new air, oil and fuel filters, eight new spark plugs, new alternator and power steering drive belts, a new battery, and a change of engine and gearbox oil. All-in-all, he spent almost £4,000 doing all the jobs, large and small, that most people would have ignored, all of which have been diligently recorded on a 4-page spreadsheet for the new owner to appreciate, digest and enjoy…
The gearbox, rear differential, and overdrive have also been reconditioned and the car has been partly rewired and a new starter motor fitted in the near past. Again, all recorded and neatly listed.
