Hydraulic Flat Tappet 4/7 Swap Camshaft

The Summit Racing SUM-1202 is a high-performance hydraulic flat tappet camshaft engineered specifically for Chevrolet small block (SBC) applications. By utilizing a 4/7 swap firing order, this camshaft provides improved mixture distribution and smoother engine operation through equalized crankshaft journal loading. It is built using ultra-modern lobe technology to maximize performance within a 1500 to 5800 RPM operating range, making it a reliable choice for racing scenarios. While this component is a core part of an engine build, successful operation requires matching the valvetrain to the specific cam profile. Proper installation is critical for flat tappet camshafts, particularly regarding the break-in process. Users should follow standard engine break-in procedures to protect the camshaft lobes and lifters from premature wear. This part is intended for SBC architectures; ensure your specific engine head and induction setup are configured to support the performance gains expected from a 4/7 swap grind.
