INTAKE MANIFOLD

INSTALLATION INSTRUCTIONS

This instruction sheet is designed to cover a wide variety of vehicle applications. If your vehicle is not equipped with the

items referred to in these instructions (EGR, transmission kick-down linkage, air conditioning, or power brakes), proceed to

the next step.

Thank you for choosing WEIAND® for your manifold needs. It is our concern that you follow these instructions carefully, so that you

can achieve the desired results. Slight errors in installation can make a big difference in performance, mileage, and emissions.

Warranty is void, if proper installation procedures are not followed. PLEASE READ THE INSTRUCITONS COMPLETELY BEFORE

BEGINNING INSTALLATION.

IMPORTANT: Although all WEIAND® parts pass several inspections, it is imperative that the installer personally inspects the part

before installation. Run a stiff wire through all passages while shining a bright light into it. Also, wash the part using

mild soap and water solution. Check the fit on all bolt holes for proper alignment and thread any fittings in first by hand.

Failure to perform these simple checks could result in engine damage and may void your warranty.

APPLICATION: The WEIAND® 8010 ACTION PLUS manifold has been designed to be used on 351M and 400 (Wedge) Ford

engines. These 180° dual-plane manifolds are designed as a stock replacement manifold with improved power and torque. The

effective RPM range of these manifolds is off idle through approximately 6000 RPM. The carburetor-mounting pad is designed to

accept either a stock or aftermarket carburetor. Combined with WEIAND’s dyno-matched cam kits, the ACTION PLUS series provide

the ultimate in economical street performance. The ACTION PLUS manifolds have been designed to accept most stock hardware,

such as coolant and vacuum lines, coils, and brackets. Little alterations, if any, will be required.

5. If you had to remove your distributor, install it at this time. Make sure that your distributor engages the oil pump drive shaft. 6. Check the location of the rotor and distributor body, making sure your reference marks line up. Refer to ignition removal section (steps 2, 3, & 4). Tighten the distributor body just enough that it can still be rotated by hand. 7. Install all water sensors and vacuum fittings into the manifold.
