BCBC CASC-3 Engine Camshaft

OE Replacement Camshaft for Cadillac V8 Engines

The Melling CASC-3 is a stock replacement engine camshaft built for Cadillac applications that call for an OE-style hydraulic flat tappet profile. It is made in the USA and engineered to match factory engine requirements for torque, economy, and horsepower balance.

• Hydraulic flat tappet camshaft with standard replacement grade
• Computer controlled compatible for applicable engine management systems
• Intake and exhaust timing profiles set for stock-style drivability
• Made in the USA with OE replacement focus

Camshaft Profile and Application

This Melling camshaft uses a hydraulic flat tappet design with 0.425 intake valve lift and 0.465 exhaust valve lift. Duration figures of 194 degrees at .050 inch lift on the intake side and 210 degrees on the exhaust side support a stock replacement grind for Cadillac DeVille, Cadillac Eldorado, and Cadillac Commercial Chassis applications, along with other listed Cadillac models. The CASC-3 is intended for buyers restoring or maintaining original-style engine behavior in Cadillac Calais, Fleetwood, Series 62, Series 60 Fleetwood, and Series 75 Fleetwood applications.

This part cross-references Standard Ignition S-554 for the same application.

What This Camshaft Helps Address

• Worn cam lobes that reduce valve action and engine performance
• Loss of low-speed torque from an incorrect or worn cam profile
• Rough idle caused by a mismatched replacement camshaft
• Drivability issues when restoring stock engine timing characteristics

Installation Notes and Tips

Verify engine code, valve train setup, and camshaft specifications before installation. This camshaft is a hydraulic flat tappet design, so lifter compatibility and proper break-in procedure should be confirmed during assembly. Match the camshaft to the intended Cadillac engine application and check timing components, rocker ratio, and valve train clearances during service.
