Block Huggers Street rod style, center exit
These headers are manufactured using fully CNC mandrel bent thick wall aluminized tubing, TiG welded in a fixture, with 3/8 flanges, that are machined flat after welding for a reliable seal.
They are a mid-length design, with 1 3/4″ primaries and 3″ collectors, designed for optimum performance from stock to performance builds. Higher end builds (over 500 real HP) may benefit from larger tube headers, but the 1 3/4″ headers perform well in most street combinations well into the mid-600-HP range. On most stock and street performance builds, these headers beat anything else available, on the dyno.
Note: These headers are not suitable for most 49-newer applications. Known exceptions: Tri-5 (’55-’57) Chevy cars, most ‘real’ Jeeps (CJ-series), and some 4×4 trucks without a crossmember under the engine.
By definition, ‘block hugger’ headers are a center exit design, pointing straight down, where most modern cars and light trucks have an engine crossmember that will interfere.
Note: The 1 3/4″ version is a Cad Company product, and is substantially tighter to the block, and noticeably better quality, than the 1 7/8″ version available here, or the dirt cheap imported stuff found on e-bay, etc. (not Cad Company products)
