Engine Sealing

Ford Racing Circle Track engines use a 1" (25.4 mm) diameter cap seal with FRT 6-digit
serial number. Factory built engines are sealed at the factory by 6 seals in 3 locations:

• Oil pan rail – left and right side

• Front cover – 2 on the top left and right of the front cover

• Intake Manifold – one on the drivers side front and one on the passenger side rear

No part of this document may be reproduced without the prior agreement and written permission of Ford Racing

Cap plug seals are a two piece design.
The base is secured by the bolt and
encapsulates the head of the bolt. This
base includes fingers that interlock with
the cap when installed. Any sign of
tampering or removal is easy to detect.

Ford Racing 347 Series Sealed Engine Handbook

Shown below is a close-up of the Ford racing factory seal with "FRT" and 6 digit seal number
with each seal having a unique number. Ford Racing maintains complete records of each
Factory Original seal number, its location and the engine to which it belongs.

Oil pan seal location – one on each side of the oil pan

Sanctioning Body Sealing – Each sanctioning body is encouraged to use the Ford Racing
Factory sealing process of cap seals should engine teardown or repairs be necessary. Note
that Ford Racing will not issue replacement cap seals.

Crankshaft Identification

Ford Racing 347 Series Sealed Engine Handbook

The SCAT Part number is
located in the first counterweight
but is often partially hidden by
the balancing heavy metal and
the metal finishing of the area

There may be light
grinding on the side of
the rod throw for final

All of the rod throws have a lightening hole as shown

Tech Specifications for Inspection

Hydraulic Valve Lifter

• The inner plunger diameter of all generation lifters and found that dimension to be

0.6165” +/- .0007”

• Lifter preload maximum of no more than 1/2-3/4 (0.025-0.040”) turn would be
appropriate from a performance standpoint.

• Lifter plunger travel is 0.145”-0.160”

• NOTE: 0.110”-0.130” flat washer is used under the rocker arm stud in some production

heads to achieve the correct poly-lock thread engagement on the rocker arm stud

Valve Spring Installed Height

• Valve spring installed height achieved by +0.050” valve locks or valve spring shims.

Pushrod Length

• To accommodate the different brand roller rocker arms used in production,
pushrod lengths of 6.500” – 6.800” in length are used in the production D347SR
engines

Typical Ford Racing Production Valve Job Characteristics

• All seat angles are confined to the seat insert with the top cut extending past the
edge of the seat into the combustion chamber

• All seat cuts are concentric to the valve stem centerline

Identification of M-6049-Z304DA Heads used on M-6007-D347SR Engines

Note that the M-6049-Z304DA Heads have been used on various Ford Racing Crate
Engines since 2006. Earlier heads from these street crate engines were not factory
installed on Ford Racing M-6007-D347SR Sealed Racing Engines. The heads used
to build all D347SR Sealed Racing engines can be identified by the size of the intake
port opening. ALL D347SR Sealed Racing Engines use a casting with the same
intake port dimensions with no exception.

Maximum Intake Port Opening

Width – 1.305”

Height - 2.205”

D347SR Sealed Racing Engine Valve Option

Ford Racing 347 Series Sealed Engine Handbook

Effective January 1, 2011, a 7MM intake and exhaust valve for the M-6007­D347SR engine has been added as a replacement option. It will be the
option of the sanctioning body to approve the use of these valves for
competition.

The approved valve is sourced only from REV and is a solid stem stainless
steel valve.

The approved part numbers are:

• 7MM Intake valve - Ford Racing M-6507-D3047 or REV PN X813

• 7MM Exhaust valve – Ford Racing M-6505-D3047 or REV PN X914

• 7MM Valve guide – Ford Racing 502-7MM-210-E6 or REV PN VG9450

uses steel valve locks, the 13171-8 titanium valve lock is removed as an alternate PN in revision #7.
