truck is ready for any pre-run
in the desert or a full-on race.
Upgrading
The Engine
Originally, the truck had a
modified 302 cubic inch V8
engine when it competed in
SCORE and other racing events.
For Yeiser, a small-block making
around 400 horsepower
wouldn't do in his vision of
the truck. Instead, he opted
for a 460 cubic inch big block
that makes 1200 horsepower
and 900 lbs.-ft. of torque.
To achieve this power level,
Yeiser sought the help of NCP
Motors in Diamond Springs,
California, to build a twin-
turbo, fuel-injected engine.
The project began by
balancing and blueprinting
the block and cylinder heads,
then adding a set of JE 8.5:1
compression pistons and
Eagle H-Beam connecting
rods to the Ford modular
crankshaft. A Competition
Cams camshaft was used to
control the flow of air and fuel
to the combustion chambers
which work in tune with the
Turbonetics turbochargers that
create up to 14 psi. of boost.
The engine operates with
an AEM control module and
uses a long-runner Hogan
aluminum intake manifold
that has been outfitted with
Blackhawk fuel injectors. The
system gathers in air from
two UMP air intake canisters
