This is our most popular Hemi intake manifold. Ray developed this model many years ago because there was a huge demand for a purpose built single plane intake suitable for big cubic inch Hemi’s. To check for hood clearance use 6.875” as the distance between the top of the block and the carb mounting surface.
- 50 HP gain over dual plane intake manifolds

- Lots of material to allow porting for big HP applications
- Easily adapted to EFI with no welding required
