Show original supplier description
The Speed Engineering SBC Longtube Headers are engineered to enhance the performance and sound of your C10 or K10 truck equipped with a 5.0L (305) or 5.7L (350) Small Block Chevy V8 engine. Crafted from durable, natural 304 stainless steel, these headers boast mandrel-bent tubing for unrestricted exhaust flow and are TIG welded for superior strength and longevity. Key features include 1 5/8" primary tubes that transition to 1 3/4" x 1 1/2" oval ports, leading into a 3" collector. The design incorporates a merge spike to reduce reversion and improve exhaust scavenging. The headers also feature CNC machined flanges for a precise fit and come with 17 3/8" center-to-center outer bolt holes. This product is explicitly designed for V8 engines only and is intended for competition use. These longtube headers are compatible with 1960-1987 C10 and K10 trucks. However, some transmission linkages or Z-bars may require modifications or relocation for proper fitment. It is important to note that this product is manufactured and sold for installation on vehicles intended solely for competition purposes. Use on public roads or highways is prohibited and may violate environmental regulations.
