Steve Dulcich suggests that the impact of headers is less significant when used with a smaller cam compared to a larger one. To explore this idea, the team examines the power increase in their Ultimate Average 383 engine, testing factory-style manifolds, shorty headers, and full-length headers first with a modest 200/206 cam, and then with a beefier 230/236 cam. They aim to determine whether a smaller cam sees fewer advantages from upgrading to headers.
