The next step was installing the new timing set. The COMP Cams No. 2100 set features an induction hardened cast-iron camshaft gear, a billet steel crank sprocket, and a three-key crank sprocket for 4-degree incremental adjustability and 4-degree maximum advance/retard. It also utilizes a heavy-duty, heat-treated true double roller timing chain that's ideal for the street performance applications Barkley was looking to achieve. Also, it's important to note that it's extremely important to use quality fasteners (like the ARP bolts, nuts, and studs used throughout the build); the extra expense is worth every penny when compared to the time and money invested in any build.
