DESCRIPTION: The Edelbrock CH-6B intake manifold is designed for 440 c.i.d. Chrysler engines with 3 x 2-barrel carburetors. Manifold also fits 413
and 426 (wedge) c.i.d. engines. It is a stock replacement/street legal part for 1968-1971 440 V8 engines with OEM 3 x 2-barrel carburetors. This
manifold was original equipment on Chrysler 440 Six-Pack engines (Chrysler #P04529056). Will not fit 1962-1964 Max-Wedge cylinder heads.

• ACCESSORIES & INSTALLATION ITEMS: Major recommendations are listed below. See our catalog for details. To order a catalog, call (800)
FUN-TEAM, or visit www.edelbrock.com.
• EGR SYSTEMS: These manifolds will not accept stock EGR (exhaust gas recirculation) equipment. EGR systems are used on most 1972 and
later model vehicles. Check local laws for requirements.
• CARBURETOR RECOMMENDATIONS: This intake manifold uses three 2-barrel carburetors; a center carburetor (usually equipped with the choke
housing), and two outboard carburetors. Reproductions of the OEM center and vacuum operated outboard carburetors, the appropriate linkage,
and additional installation parts are available through Mopar Performance. Contact your local Chrysler/Dodge dealer for more information. You
may also use OEM replacement, mechanically operated outboard carburetors (available through various other manufacturers). Use the supplied
linkage parts as needed. Some modification may be necessary.

NOTES: Some applications, such as race engines, may decide to use non-OEM style 2bbl carburetors. If this is the case, carburetor size (CFM)
should be selected based on your specific engine combination. Consult your engine builder or contact our Technical Hotline at: 1-800-416-8628
for assistance. Non-OEM replacement carburetors may require custom bracketry and linkage. Carburetors require a #8008 or #8024 stud, washer
and nut kit; determine proper length based on gasket thickness and your accessory mounting requirements (See catalog for details).
• GASKETS: Do not use competition-style intake gaskets for this street manifold. Due to material deterioration over time, internal leakage of
vacuum and oil may occur. NOTE: YOU MUST USE a factory metal valley tray gasket along with the Edelbrock gaskets listed below.
If your stock valley tray is in good condition, it may be reused.
