This manifold is cast and precision machined to provide an exact fit with Screamin Eagle Pro Accessory cylinder heads and the Screamin Eagle Pro 58mm EFI Throttle Body P/N 27639-07A.
- This manifold has intake runners which are .100" larger in diameter than all stock Twin Cam heads and early Screamin Eagle performance cylinder heads
- The intake port diameter in the cylinder heads should be 1.750", if not, an experienced engine builder can open the cylinder head ports to this diameter to ensure a smooth transition and air-flow
- Stock injectors can be reused for applications making up to 100 rear wheel horsepower, Screamin Eagle Pro High-Flow Injectors P/N 27797-07 are recommended for engines producing greater than 100 rear wheel horsepower
