In general, the 428 is much cheaper and easier to find than
the 427. The later vintage 428 Cobra Jet (CJ) or 428 Super
Cobra Jet (SCJ) engine is fine for all-around street use,
offering from 325HP to 425HP with very good low RPM
response and tractability. Most 428 cores can have their
performance “updated” by the addition of new heads from
Edelbrock and Shelby at reasonable cost. With an
appropriate intake manifold and carburetor, a 428 will put
out over 400 streetable bhp.
The 427 "Side Oiler " is the legendary Cobra engine. Its
cross-bolted main bearings, improved oiling system and
shorter stroke are modifications made for racing. It is more
reliable above 5500 RPMs, with somewhat better high RPM
power than the 428 (and a little less torque at low RPMs.)
Many of our customers have built 427CID engines of more
than 550BHP. We have found that the extra money spent
on a 427CID engine will usually be returned in a higher
resale value for the finished car.
The 427CID Center Oiler is now found mostly in boats. It
lacks the exotic oiling system of the Side Oiler while
retaining its bore and stroke. Since it was never found in the
original Cobra, it lacks some internal authenticity, but it
does
look correct. There are a few problems associated with
converting boat engines to car use. Many boat engines
rotated in the reverse direction, with counter- camshafts,
incorrect crankshaft sealing, and oddball distributors, among
other things. Use caution.
A hybrid 454(+)CID engine may be created by the use of a
428 crankshaft in a 427 block, using Chevrolet pistons and
other special efforts. This is not an engine for the
inexperienced to build, but it's great fun to drive, with good
horsepower and flexibility.
Aluminum blocks are available from Carroll Shelby
Enterprises, Genesis, Pond, and Dove Engineering. Shelby,
Edlebrock and Dove make aluminum cylinder heads.
For the more adventurous, E.R.A. has modified footboxes
and steering column to fit the
Ford 427 SOHC . With its
huge ports, this engine produces a lot of horsepower, but has
poor low speed flexibility. Because of the width of the
heads, there is a significant loss of
foot room . Primary
exhaust pipes must be custom made.
Alternately, you may also build an economical variation to
the 427/428 FE using a 390 block. Externally, this engine is
identical to the 427/428, and it accepts most of the same
performance parts.
FLYWHEEL
The FE flywheel should use a ring gear with 184 teeth, not
153.
INTAKE MANIFOLD:
Low and medium-riser intake manifolds (including the
Edlebrock Performer) can be used on the E.R.A. 427SC
without modification.
The manifold may have to be tapped for the temperature
gage fitting. See notes on page 32.
CARBURETORS
A single 4-barrel Holley carburetor will connect directly to
the linkage supplied with the kit. Since the carburetors are
turned 180° in the dual 4-barrel carburetor installation, you
must either use the factory Ford linkage (which crosses the
intake manifold between the carbs) or fabricate new linkage.
All 4 bbl carburetors can be run
without chokes with only
slight driveability limitations. If the choke plate is removed,
the choke housing should also be removed for extra
clearance to the air cleaner. Street hoods (without scoop)
require this extra clearance with some intake manifolds.
Inglese Induction (now part of Total Performance,
Wallingford, Connecticut) has developed a 4 carburetor
Weber 48IDA configuration for the FE block. While this
really looks impressive, it takes a lot of tuning and a
perfectly-set-up linkage for a minimal gain of power – not to
mention being expensive.
FUEL PUMP
We use a heavy-duty mechanical fuel pumps (Carter
M6905) on both 427 and 428 engines with no problems. If
you don't need the extra capacity of an electric pump, avoid
the complication and noise. (Wiring for an electric pump is
built into the standard wiring harness.)
OIL FILTER
Any standard block mounted oil filter equivalent to the
Motorcraft FL1 HP may be used. The same Ford part can
be used on the remote filter supplied with the oil cooler with
remote filter. The optional remote filter mount (usually
integrated with an oil cooler) uses a Transdapt 1015 block
adapter.
OIL PAN
There is a limited distance between the engine and the
ground. Use a pan with a
maximum depth of 6.5 inches.
For more oil capacity, there are pans available that are
wider. Canton and Aviaid make good designs. E.R.A.
normally stocks Canton pans both in a high capacity street
design and the Road Race design. Part numbers are on page
24. Some Aviaid pans have two additional fittings at the
right front: A large tube that’s intended to connect to a
breather tank and a smaller tube that can be used for a
dipstick. Plug them with metal if not used.
ALTERNATOR AND PULLEYS
ERA supplies the alternator mounting bracket to shift the
alternator up and in from the original location. An adjusting
bracket (to replace the stock one) is optional.
You may use a single groove pulley system for the crank,
water pump and alternator. Aluminum pulleys from March
Performance work well. For street use, we don’t
recommend underdriving either the alternator or water
pump.
