BBC Roller Cam - 4 & 7 Swap 47S318RXD-14

The COMP Cams BBC Roller Cam — 4 & 7 Swap 47S318RXD-14 is a precision-engineered roller camshaft designed for big-block Chevrolet engines, ideal for both oval-track and street performance builds. This camshaft is specifically designed for engine swaps that require compatibility with both 4-bolt and 7-bolt drilling patterns, making it perfect for builders upgrading or transitioning between classic BBC blocks.

Roller cams like the 47S318RXD-14 offer higher efficiency and durability compared to flat-tappet designs, enabling aggressive valve timing while minimizing wear on cam lobes and lifter surfaces.

This camshaft's roller design reduces friction loss and allows for steeper ramp rates, resulting in quicker valve opening and closing events that optimize engine breathing at high RPM.

Hot rodders, oval-track competitors, and street builders will find this camshaft particularly beneficial, as it provides reliability and performance without the need for frequent maintenance. The "4 & 7 Swap" designation ensures compatibility across different block configurations, making it a versatile choice for various applications. Installation requires proper valve train setup to maximize the benefits of this high-performance camshaft.
