Chevy Small-Block ProCharger F-1R-103 Modular Accessory Drive Kit

ProCharger 1CA400 pairs the selected F-1R-103 head unit with the Chevrolet Small-Block modular accessory drive.

Package configuration

Straight-cut gears and 8-rib supercharger drive included. Helical gears are not offered on these F-series heads. Choose non-intercooled or 3 core 1300 hp intercooled configuration. Intercooler ratings describe capacity, not guaranteed engine output. A Race Valve is included. The intercooled configuration includes tubing and a 3.5-inch intercooler outlet; the non-intercooled configuration does not include charge tubing. Full accessory brackets support alternator, power steering and A/C; the accessory units are optional.

Finishes and bracket layout

Full accessory brackets: satin, black (+250 dollars), or polished (+350 dollars). Satin-only omission choices deduct 300 dollars for power-steering hardware, 200 dollars for A/C hardware, or 500 dollars for both. Supercharger housing finish: satin, black (+295 dollars), or polished (+450 dollars). These adjustments are included in the selected variant price. Supercharger-bracket finish and accessory units are selected separately.

Engine and installation fitment

For custom Chevrolet Small-Block engine installations. Provide block manufacturer, casting, displacement, deck height, cylinder heads, crank balancer, water-pump configuration, chassis and accessory clearances for application review. Uses a compatible short reverse-rotation water pump, CS-130 alternator with 6.14-inch mounting-bolt spacing, GM compact Type 2 power-steering pump and Sanden SD7 six-rib A/C compressor where fitted. Confirm the exact components and pulley alignment; accessory units are supplied only when separately selected.

Build requirements

Provide induction type, target boost, maximum RPM, fuel system and tuner. Fuel-system upgrades, calibration, charge plumbing and vehicle integration must be planned for the specific build. Engine-family compatibility does not establish direct vehicle year/make/model fitment. Carburetor hat selection requires compatible blow-through induction and clearance review.

Manufacturer configuration images are references, not an exact packing list. Supplied head unit, finishes and accessories depend on the selected package and add-ons.
