Speed Engineering LS Swap Longtube headers are made out of 304 stainless steel and offer great quality, performance, and affordability. Our LS swap longtube headers are mandrel bent, tig welded, and feature natural stainless steel construction. All of our LS swap longtube headers have been dyno proven. We stand behind our LS swap longtube headers in saying you will not find a better fitting, quality built, budget header for your vehicle.

Features include:

  • Mandrel Bent Tubing
  • 1 3/4" Primaries
  • Longtube Header Design
  • LS Swap Conversion Header
  • Perfect Ground Clearance for Air Ride & Lowered applications
  • Works on factory & most aftermarket chassis Porterbuilt, Choppin Block, ect.
  • 3" Collector
  • V8 Engines Only
  • Merge Spike
  • 4.8L, 5.3L, 6.0L, 6.2L, LS1, LS2, LS3, LS6, LSA Engines
  • CNC Machined Flanges
  • Natural 304 Stainless Steel
  • Standard Graphite Manifold Gaskets

Vehicles:

  • 1960-1987 C10 Trucks
  • (1960-1966 C10 Trucks require slider engine mounts to clear the front crossmember)

Note: Headers do not hang below the frame and offer ground clearance with air ride suspension and lowered suspension. Customers have installed this product on Choppin Block, Roadster Shop, Porterbuilt, and other front drop members with air ride and coil over suspension.

Note: "Due to older vehicle frame clearance headers are pulled in very tight, and require our spark plug wires".

Note: "For LS series engine swaps only" These do not work on standard SBC or BBC engines.

Note: If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance.

Note: "Does not fit 4wd"

Fit great

Highly recommended installed on a 1984 C10 I run a 5.3 with a TH400 only thing I had to do was cut a ear off my transmission just as the instructions on the web said so I like them

LS/NV4500

These headers look great, but you cant run them with a manual transmission they hit the clutch linkage. Went with the short/huggers instead. Great product regardless.

Perfect Fit

They fit perfect on my 78 C10 gen 3 5.3/60e swap. My engine mounts are cheapo slotted adjustable ones from Amazon (for fit reference). They fit in the all the way forward and aft positions. They are actually stainless and are uncoated polished so they'll change colors after a few heat cycles (mine are a light gold color now). They came with bolts also! I would definitely recommend them!
