413-440 c.i.d. Big Block Chrysler Engines Pro-Flo XT Intake Manifold Installation

4:59 AM by onesecond ·
The Edelbrock Pro-Flo XT intake manifold is designed to allow the use of electronic direct port fuel injection on big block Chrysler engines. The height of the manifold from the end seal is 9.09” at the front and 8.20” at the rear. This intake manifold features a log style plenum and large free-flowing tunnel ram style runners. The throttle body flange can accomodate a bore of up to 90mm and is intended for use with the Pro-Flo XT throttle body, part #3869, for right side linkage applications, or Ford style throttle body #3818 for left side throttle linkage applications. A provision for installing an LS1-style MAP sensor has been drilled and a separate mounting bracket is supplied.

Installation Procedure:
1. Use only recommended intake gaskets set when installing this intake manifold.
2. Fully clean the cylinder head intake flanges prior to applying gaskets.
3. Apply Edelbrock Gasgacinch sealant P/N 9300 to both cylinder head flanges and to the cylinder head side of the gaskets, allow them to air dry, then attach the intake gaskets.
4. Apply a coat of Gasgacinch to the top side of the intake gaskets, allow them to dry slightly, then install the factory valley pan gasket.
5. Install the intake manifold and hold-down bolts, following the torque sequence shown below.
