Buick 455 Engine Bolt-Ons - Epic Buick 455 Dyno Thrash

This dyno graph compares the B4B intake (blue lines) with the SPX intake (red lines) while using the small TA-212 camshaft. Note the textbook trade-off between low-end gains with the dual-plane and high-end performance with the single-plane. In this case, we'd choose the dual-plane.

This graph compares the most low-end-friendly combo of the small cam and the B4B intake with the best high-rpm combo of the larger cam and the SPX intake. On average, they make the same power. But which would you choose? It depends on your performance goals, street or strip.
