Description

The Speed Engineering SBC longtube headers are a direct-fit exhaust upgrade for 1971-1993 Chevrolet Impala and Caprice B-body vehicles equipped with SBC 5.0L/305 and 5.7L/350 V8 engines. These headers are constructed from 304 natural stainless steel and feature mandrel-bent tubing for consistent diameter and maximum flow. They include a 3" collector with a merge spike for optimized torque and CNC-machined flanges for a leak-free seal. Standard graphite manifold gaskets and 10x1.5x25 zinc header bolts are also included.
