The BSP-2 Ground Camshaft for GX200/Clones is for the Box Stock class. Meets rule specs. The center-lines of this cam are slightly further apart than the CL-1i cam because the intake lobe has been retarded 3°. This helps top end RPM making this a great cam choice for an unrestricted or blue plate box stock engine. Also fits the Harbor Freight "Hemi" Predator.
