Chevy Big-Block ProCharger F-3R / F-3D Standard Rotation Cog Race Kit

Big-block Chevrolet ProCharger F-3R / F-3D cog race kit in the standard rotation configuration. Catalog family: 1CB200-F3R-spec. Select the head unit and supply the exact engine and installation details before ordering.

Race hardware

The manufacturer specification lists a 14 mm-pitch, 55 mm-wide cog drive and ProRace bypass valve for the F-3 kit family. These are non-intercooled kits; charge cooling, induction plumbing and the fuel and calibration system must be specified for the actual engine combination. Do not assume a carb bonnet or accessory relocation hardware is included.

Engine and installation fitment

For custom big-block Chevrolet race installations. This is engine and accessory-layout fitment, not blanket compatibility with a vehicle year or model. Supply displacement, deck height, cylinder heads, crank/balancer arrangement, V-belt or serpentine accessories, induction type, chassis and available clearance. Review mounting, rotation and drive alignment before purchase.

Configuration

Selected variant pricing identifies the specified F-3R or F-3D model. The catalog uses a specify-model suffix; the shop SKU distinguishes each selection. F-3R-112 was formerly called F-1X-12. Satin is standard. F-3R 12-inch housing finishes add $650 for black or $750 for polished. F-3D 10.5-inch housing finishes add $395 for black or $500 for polished when offered in this listing. Housing finish is included in the selected variant price; bracket finish is separate. No boost or horsepower output is guaranteed; fuel delivery and calibration must match the complete build.

F-3D-102 and F-3D-106 are catalog alternatives to F-3R-112, reducing the satin kit price by $500. Confirm the selected head and mounting combination before ordering.

Dimensional reference

The gallery includes the manufacturer's SBC/BBC V-belt accessory dimension table and its A–H measurement key. The key is illustrated with a D-1SC and is not a photograph of the selected F-series kit. Use the row matching the engine block and supercharger family, and confirm the exact head unit, mounting and accessory arrangement before installation. These references do not establish reverse-rotation clearance or vehicle fitment.

The head-unit photograph shows the manufacturer's F-3D-106 on display stands, with and without an inlet bell. It is a head-unit reference, not a complete kit photograph or a representation of every F-3R/F-3D selection. Display stands and pictured inlet accessories are not promised as kit contents.
