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 7/8" Primaries
  • 3" Collector
  • 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.
  • Merge Spikes
  • V8 Engines Only
  • 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"

They fit perfect

They fit perfect in my 88 Ls brougham caprice classic with no problems . Didn’t have to modify or adjust anything . Bolted up fine and fit in there perfect & yes it’s they’re on my LS motor ( did a LS swap )

Nice fit and finish

Fit my 72 c10 6.0 LS swap very well. These are easily the best bang for your buck headers.

Highly recommend

I bought these for a 1970 c10 with a gen 3 5.3 ls and 4l60e trans swap. They fit great. Installation was easy, the don't come in contact with the frame or trans or anything and aren't overly priced either.

These are excellent

I purchased these in person in the shop today, I was a bit nervous about their fit because so many big name places claim theirs will fit 73-87 C10s but many do not fit at all. These are a perfect fit and require zero cutting of the frame or crossmember. The only modification these needed to work on my truck is a simple one. Cut the passenger side transmission ear off with a grinder. To be fair this is likely because I'm using an early style 4L80E. I couldnt be happier with this product. Well done, Speed Engineering. Just so we're clear I'm in no way paid to leave this review and I do not work for/with Speed Engineering. I'm just a happy customer who is very glad to pass along the good news to fellow 73-87 C10 owners. Now theres more options than just Trail Blazer SS headers, which can be very expensive.
