CRATE ENGINES
CAMMER ENGINE
“CAMMER” ENGINE
Not long ago, the term “dual over-head cam
engine” was reserved for the high-tech racing
community. Although the DOHC technology
employed in mainstream production engines is
almost commonplace today, the technical
procedures to machine and assemble a
modern DOHC engine are rather complex.
Compared to the Windsor-based Ford V-8
engine family, the modular four-valve engines
require greater attention to detail regarding
machining, torque sequences, and number
of fasteners (i.e. the overall complexity of
the assembly process itself). The following
photographs offer an inside look at the build
of a 4.6-liter dual overhead cam V-8 down
the same line as the 5.0 “Cammer.”

After honing,
all cylinder bores
are inspected for
concentricity and
final finish.
Cylinder heads are checked with 27.5 inches of
vacuum to ensure the integrity of valve sealing.
A CNC machine is used to bore
the cylinders on center, deck
the block, and chamfer the tops
of the cylinder bores.
The main bearing cap bolts are torqued down
to spec by an automated torquing machine.
Finish-honing of the
cylinder bores is
accomplished via
a Gehring CNC hone.
