All Ford Racing crate engines start as an idea. The Ford Racing
engineers begin with a horsepower target and the engine family for
hitting that target. Then, Ford Racing documents the components that
will likely achieve targeted horsepower and meet durability
requirements. This procedure is based on Ford Racing's years of
experience in the high-performance crate engine building business. Many
formulas also support this process. Next, Ford Racing has one or more
development crate engines built and sent to the engine dynamometer lab
for break-in and testing. During dyno-testing, fuel distribution, best
cam timing and best ignition timing for maximizing horsepower and
torque are assessed. If target performance numbers are not met—or can
be improved—changes are made accordingly. Often times, different
carburetors, camshafts, intake manifolds and cylinder heads are
evaluated. After target numbers are reached, the Ford crate engine is
run for durability. Durability testing is based on the market
application of the Ford crate engine. Various durability tests may be
run—sometimes as severe as 50 hours at wide open throttle, full power.
Others may be cycling tests where the Ford crate engine accelerates
from peak torque to peak power, then decelerates back to peak torque,
then repeats the cycle for many hours. The tests selected vary
depending on the market application. Upon successful completion of
durability testing, the Ford crate engine package is released for
production.
