DESCRIPTION: Super Victor BBC manifolds are designed for competition vehicles only. They are not intended to be
used on the street as there are no provisions for chokes, emission components, etc. Tall-Deck versions are intended
to be used on 10.2” deck blocks with no need for manifold spacers, and will accept standard length distributors.
NOTE: It is the responsibility of the end user to verify conformity to a particular racing association’s rules

NOTE: It is the responsibility of the end user to verify conformity to a particular racing association’s rules
regarding manifold dimensions, fitment to a template, etc.
•
CARBURETOR RECOMMENDATIONS: Use an appropriate 4500 series racing carburetor (CFM will vary according to
your application).
your application).
•
CARBURETOR SPACERS: Both engine dynamometer and in-car tests have shown additional torque is available by
the use of a one-inch thick, open (not 4-hole) carburetor spacer (# 8717) on the Super Victor manifold.

MANIFOLD TORQUE: Torque the manifold bolts to 25 ft/lbs in small, even steps, following the recommended torque
sequence

(See Fig. 1). If you cannot fit a torque wrench on some of the bolts, use a small box end wrench to avoid
over tightening.
•
INTAKE GASKETS: As cast manifolds will fit well with
Fel-Pro #1211 intake gaskets. CNC versions are
matched to Fel-Pro #1275 gaskets.

PREP AND TUNING FOR POWER: Optimum cylinder
head port opening size should be as close as possible
to the size of the gasket being used. Port-match the
manifold exits .020” per side smaller than either the
gasket being used, or the cylinder head port opening,
whichever is smaller.

NOTE: As cast models only.
CNC models do not require port matching when
used with the recommended gasket.
•
END SEAL CLEARANCE: Due to varying deck heights
and/or valley widths, either from decking the block or
milling the cylinder heads, the end seal clearance
should be checked. Lay the manifold on the engine with gaskets in place, and measure the clearance. There should
be a minimum of .060” between the block surface and the end seal surface of the manifold. You may need to machine
the manifold flanges or end seal surface to achieve optimum clearance.
