Overview:
64-92 GM F, G, & A Body SBC Mid Length Stainless
Mid-Length Headers, often called Clipsters, are engineered to provide superior performance gains over Manifold Replacements or Block Hugger style headers. These headers enhance your vehicles's horsepower and torque while preserving ground clearance for cars with a lowered stance and trucks where long tube headers may hang to low. This fitment is tailored for popular aftermarket engine swap kits. Doug's engine swap headers were developed to solve common fitment issues in tight spaces, making your swap process smoother. No more guesswork or modifications needed - just straightforward installations that save you time and frustration.
Features:
- Natural stainless-steel finish offers superior resistance to rust and corrosion
- 3/8" thick 304 stainless machine flanges to prevent warping
- CNC 304 stainless mandrel bent tubes for an accurate fit and improved flow
- Precision formed long transition collectors and long tube design reduce backpressure and increase higher RPM horsepower
