1970-81 GM F-Body LS Swap Components

The 2nd Gen Camaro/Firebird with its large mouth grille has the look that just needs to be modernized. Holley has engineered a complete system to swap the mild small block to a ultra-modern LS. From fuel to exhaust with all mounts and accessories, Holley has the complete system to take your 2nd Gen to the next level.

Hooker cast iron exhaust manifolds have been designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications. Their contoured design aims the exhaust directly at the exit port for improved flow. Being cast iron means they will provide years of leak-free performance with less under hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.

Highlights

  • Intended for all GM LS (except LS7 and LS9) engine swap applications where durability, quiet operation, emissions compliance and leak-free sealing is desired
  • Available in plain as-cast finish or with various Hooker ceramic coatings for reduced engine compartment temps and improved corrosion resistance
  • 304 stainless steel mating flanges included (mating flange fasteners are not included)
  • 2.25-inch outlet diameter
  • 2 bolt exit flange configuration matches 2010 Camaro (also the same as the E-rod exhaust manifolds) which can be used with OE gaskets and fasteners if desired, for an OE quality seal
  • Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
  • Free-flowing for good performance and catalytic converter efficiency
  • Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance - ideal for GM E-Rod installations
  • Recommended for strong performance on engines making up to 500 horsepower (For optimum high rpm performance see Hooker long tube engine swap headers)
  • Perfect compliment to Hooker engine swap mount plates and Holley engine swap oil pans
