Pro BBC 4-7 Swap hydraulic roller camshafts are offered in a dozen versions to cover street/towing, street/strip, and drag race applications. Each cam features a 4/7 firing order, requiring the re-routing of spark plug wires for 1-8-7-3-6-5-4-2. Cam button, a melonized or composite distributor gear, and billet compatible fuel pump pushrod are required. Choose your level of performance.
Additional features and notes:
* Designed for beehive or lighter 1.4 to 1.500 dual springs
* Designed in 12 steps, intake closing point is most important to operating rpm
* Bigger cams with increased overlap REQUIRE more open and free-flowing exhaust for maximum mid- and high-rpm power
* Cam advance is ground-in, so install dot-to-dot
* Although the advance may seem larger than normal, it's designed for maximum power under the curve
* Track testing is recommended before altering cam advance
