Roush BD347RC 347 CI Race Carbureted Crate Engine

Description

Dominating the local drag strip requires the Roush BD347RC 347 and its purpose-built carbureted race valvetrain. Command aggressive high-RPM acceleration during intense track events. This build utilizes a reinforced Dart Iron Eagle block and a single-plane Victor intake to output brutal naturally aspirated power safely.

Key Features of Roush BD347RC Race Engine

• Dart Iron Eagle 4-Bolt Block: Provides an ultra-rigid cast iron foundation that eliminates block flex during violent high-RPM launches.
• Forged 3.400-Inch Stroker Crank: Pushes displacement to 347 cubic inches to generate brutal mid-range acceleration.
• CNC-Ported Aluminum Heads: Maximizes airflow velocity to feed the race-spec combustion chambers efficiently at 6500 RPM.
• Solid Roller Valvetrain: Delivers extreme valve lift and duration without the friction wear or float associated with flat tappets.
• Single-Plane Intake Manifold: Maximizes top-end atmospheric flow when paired with an aggressive 4-barrel racing carburetor.
• Internally Balanced Assembly: Eliminates dangerous harmonics at high engine speeds to protect internal main and rod bearings.

• Fits vintage 1965-1973 Ford Mustang drag cars needing a dedicated small block race engine
• Fits classic Ford Fairlane and Falcon drag builds requiring a high-RPM carbureted powerplant
• Fits custom Factory Five Cobra race builds demanding authentic small block dimensions with forged race internals
• Fits tube-chassis bracket drag racers looking for a reliable naturally aspirated small block

Fuel & Ignition System Requirements

Feeding a high-RPM race engine requires heavy fuel delivery and a steady high-voltage spark.

• You must bolt on a high-CFM race carburetor and feed it with a dedicated high-volume electric fuel pump system
• Connect the included MSD billet distributor to an external 6AL ignition box and heavy-duty racing spark plug wires

Installation, Break-In Oil & Priming Instructions

Proper pre-lubrication ensures your solid roller race valvetrain survives its first firing.

• Use a dedicated priming tool through the distributor bore to push oil to the top-end valvetrain before turning the key
• Fill the deep-sump race oil pan with high-zinc conventional break-in oil and complete a varied RPM cycle to seat the rings
