sports tourer built between 1970 and 1978 by the Triumph Motor
Company styled by renown Italian designer Giovanni Michelotti. The
car was launched nearly two years late, in June 1970, to a warm
welcome at the international auto shows. In the UK the Stag was an
immediate success for Triumph with a 12-month waiting list rapidly
being established and cars changing hands at well above list price.
Unfortunately it rapidly acquired a reputation for mechanical
unreliability, usually in the form of head gasket failure due to
cylinder head heat distortion, leading to overheating, along with
other issues such as the simplex roller link chains. These problems
arose from a variety of causes. The engines on the original stock
cars were notoriously fundamentally flawed. Its water circulation
wasn?t the best design, the water pump was poor and low-grade
aluminium alloy was used for the heads, it?s not rocket science,
these issues meant having to replace the timing chains every 30,000
miles and constantly making sure the engine and radiator do not
silt up. Therefore this is the only way one should buy a Triumph
Stag, customized with modern upgrades as per this particular
example, with over $77K invested in the build.Custom fitted and
equipped with GM's 350ci ZZ4 crate engine which is a true street
engine, designed to run on 92-octane pump gas with GM claiming the
ZZ4 will make a respectable 355 hp and 400 lb-ft of torque. The ZZ4
crate engine has gained cult status among vintage auto and muscle
car enthusiasts.It first appeared in 1996, and has become the
longest-running ZZ-series engine ever produced, with manufacturing
lasting until 2014. Equipped with aluminum cylinder heads, a forged
steel crankshaft, hydraulic roller lifters, and "hypereutectic"
high-silicon aluminum pistons, the small-block ZZ4 V8 boasts 5.7
liters of displacement (350 cubic-inches) and a base output of 355
horsepower and 418 pound-feet of torque. The ZZ4's power and torque
come secondary to the engine's reputation for reliability,
durability, and how it responds to tuning and aftermarket upgrades.
It could effortlessly handle 100 more horsepower with a stage 5
rebuild, with some managing to squeeze out a dyno-certified 527
horsepower using a bevy of high-performance and bolt-on parts. Like
the LS3 crate engine, the ZZ4 is from American legacy auto giant
General Motors built under the Chevrolet brand. Chevy began
production of the ZZZ series of crate engines in 1990 with the H.O
350. It came with L98 Corvette aluminum cylinder heads, a four-bolt
main, a forged one-piece main seal crankshaft, and a 9.8:1
compression ratio to produce 345 horsepower and 370 pound-feet of
torque.
