Speedmaster 1-148-007 Ford 351W Sidedraft 8 Stack EFI Intake Manifold Polished

The Speedmaster 1-148-007 is a complete 8 stack sidedraft EFI intake manifold system for the Ford 351W Windsor, finished in polished aluminum. It gives you the look of classic Weber-style induction with the tuning flexibility and drivability of electronic fuel injection. The individual throttle body design supports high-horsepower builds.

Key Features:

• Individual throttle body EFI system with IDA style throttle bodies
• Precision cast aluminum throttle bodies for idle quality and throttle response, with tight air/fuel ratio control to help emissions and economy
• Throttle body opening of 52mm each
• CNC machined, heat treated 601 cast aluminum throttle bodies
• Butterflies measured for each bore and precision machined to a close tolerance
• Butterflies secured to centerless ground brass shafts with split screws for reliability and serviceability
• O-ring seals on the lower mounting faces
• Linkage set combines throttle stops, idle controls, lever arms and joiner/balancer in one assembly
• Single screw adjustment for calibrating front to rear throttle shafts
• Bell crank with a fully indexable eccentric cable pulley, for good slow speed drivability while still reaching full throttle geometry

The recommended EFI sensor kit is PCE651.1012, and the system requires style E injectors.
