1999 Chevrolet S-10 Extended Cab �€" LT1 V8 Mini Truck, Camaro Z/28
Donor Build, Mini Truck'N Magazine Cover Vehicle Why This Car Is
Special The mini truck movement of the 1990s produced some
genuinely creative builds �€" trucks lowered, narrowed, sectioned,
and stuffed with performance hardware that had no business being
under a compact pickup hood. Most of those builds are gone now,
broken down for parts or lost to time. This 1999 Chevrolet S-10
Extended Cab is one of the survivors, and it is not a casual build.
It took over two years to complete, it earned the cover of Mini
Truck'N Magazine, and it was constructed around a Camaro Z/28 donor
car �€" meaning the LT1 350 V8 and T-56 6-speed manual transmission
came out of an actual Z/28 and were transplanted into this S-10 as
a matched, factory-paired drivetrain. To understand why that
matters, a little context helps. The LT1 was GM's performance
small-block of the early-to-mid 1990s, used in the Corvette and the
fourth-generation Camaro Z/28. It featured reverse-flow cooling �€"
the engine cooled the heads before the block, which allowed for
higher compression ratios and more efficient combustion. The
aluminum cylinder heads on this engine were a key part of that
design, reducing weight and improving thermal efficiency compared
to iron-head variants. The T-56, meanwhile, is a Tremec-built
6-speed manual that was engineered for high-torque applications and
became standard equipment in the Z/28 during this generation. It is
the same transmission used in Vipers and Cobras of the era �€" a
serious gearbox in a truck that spent its factory life with
four-cylinder options. Pairing these two components in a 1999
Chevrolet S-10 required substantial fabrication work and represents
the core of what makes this truck different from anything that
rolled off an assembly line. The build also carries legitimate show
credentials. The Mini Truck'N Magazine cover is documented proof
that this truck was evaluated by people who knew the mini truck
scene and found it cover-worthy. That is not a local car show
trophy �€" that is national publication recognition during the
height of the mini truck era. Features List - LT1 350 V8 with

The engine in this 1999 Chevrolet S-10 is an LT1 350 cubic inch V8
with aluminum heads, pulled from a Camaro Z/28 donor car. The LT1
produced 275 horsepower and 325 lb-ft of torque in Z/28 trim, and
those figures are meaningful in a truck that weighs significantly
less than the Camaro it came from. The aluminum heads are not just
a weight savings �€" they were central to the LT1's reverse-flow
cooling system, which helped this engine run higher compression
without the detonation problems that plagued many performance
engines of the era. A Spectre cold air intake has been added to
improve airflow, and dual exhaust handles the exit side of the
equation. The transmission is the T-56 5-speed manual �€" also
sourced from the Z/28 donor car, which means it was engineered and
calibrated to work with this specific engine. The T-56 in Z/28
application was built to handle the torque output of the LT1
