    Engineered specifically for '73-87 C10 Pickup LS Engine Swaps

    These headers were specifically designed to be installed with Hooker LS swap engine and transmission mounting components and exhaust systems for LS Engine Swap 1973-87 Chevrolet/GMC C10/20 2WD Pickup applications. For best fitment and overall component clearances, Hooker headers and mounting components for this LS swap application are designed with a chassis-centered engine and transmission location, which varies only slightly from the original minor passenger side offset used by GM. The engine and transmission have also been positioned to enable hassle-free installation and to promote good vehicle handling performance. The unique design geometry of these headers requires the use of specific Hooker clamshell type engine mounting brackets and Anchor brand P/N 2292 or equivalent engine mounts to ensure fitment compatibility with your car. Use of any frame stand/swap plate style mounts will not provide the engine positioning necessary for obtaining the component and ground clearances designed into these headers. Attempts to install these headers with any other type or combination of engine and transmission mounting components will cause them to no longer be bolt-in compatible with the mentioned Hooker exhaust systems.

    Important Application and Installation Note
    These LS swap engine mount brackets were specifically designed for compatibility with:
  • Hooker Headers LS Engine and Transmission Mount for 1973-87 GM 2WD Pickup
  • Hooker Headers exhaust systems (p/n 520-42537, 520-42538, 520-42539 or 520-42540)
  • Holley GM LS Engine Retrofit Oil Pan (p/n 510-302-1)
  • Holley GM LS Engine Retrofit Oil Pan 1967-69 Camaro/1968-74 Nova, Extra clearance for crossmember at the front of the pan (p/n 510-302-2, cannot be used with LS7 engines or ''stroker'' engines greater than 3.62'' stroke.)
    and accessory drive components for this application. Using ANY components other than what is listed here will result in misalignment and interference issues with these Hooker and Holley components.

    Features:
  • Not compatible with all aftermarket Engine Mount kits. Some customers may experience headers coming in contact with frame depending on kit being used
  • Designed exclusively for use with Hooker p/n 520-12621 engine mounting brackets and p/n 520-12646 transmission crossmember
  • Available mild steel or stainless steel primary tube and collector
  • Mild steel headers have laser cut 3/8'' flanges with flat-finished TIG welded port sealing; Stainless steel headers have flat-finished TIG welded investment cast port flanges
  • Premium fitment with optimized ground clearance
  • Designed to maximize exhaust flow with optimized bend geometry to deliver increased power and torque without compromising fitment
  • A key requirement when designing these Hooker LS Swap Header system was to obtain the highest ground clearance possible tucking the header tubing up into the chassis as high as was feasible while maintaining optimum engine power
  • Long tube headers connect directly to Hooker 3'' exhaust system; connection of long tube headers to Hooker 2-1/2'' exhaust system, or Hooker mid-length headers to 2-1/2'' or 3'' exhaust system requires the use of an available mid-pipe kit
