Ford 300 Inline 6 Hybrid with a 5.3 Liter Chevy LS Cylinder Head

Ken Hutchinson from YouTube Channel Tall Garage is going rogue in preparation for the 2022 No Name Nationals with an outside-the-box build. He’s crafting a cylinder head for his Ford 300 Inline 6 from a pair of Chevrolet 5.3 Liter LS cylinder heads!

As with most engine projects, Ken started with disassembly. He acquired the engine from a machine shop, so the assumption was that it is good to go, but when diving into a project like this, it’s best to be sure.

Editor’s Note: Ken is working to earn 500 subscribers to his YouTube Channel to qualify for the 2022 No Name Nationals in Sikeston, MO — Pay him a visit and subscribe, plus he has several Shorts on the channel related to this engine build.

Crafting LS Heads for a Ford 300 Inline 6

Other than a mouse nest, initial indications were that the Ford 300 was freshly rebuilt as there was no residue on the oil pick-up, and the internals looked quite clean.

As the engine came apart, signs continued to look good with little to no wear showing on the crank, connecting rods, and bearings.

With the 300 torn down and easier to handle, an initial mock-up is done with one of the 5.3 Liter LS heads.

With a mock-up and measure out of the way, Ken clamps the head to the band saw table, and makes the bold move to make the cut!

With the cuts made, which did not go quite as nicely as he’d hoped, he positions the first half head in place to further see how this is going to work. Next up: enlist the help of a friend with an end mill.

With the cuts complete, and material to spare, Ken takes the heads to a friend’s place and each half of the soon-to-be Ford 300 cylinder head is end milled on a Bridgeport for perfect fitment.

Prior to welding the two cylinder head halves into one, Ken works to ensure the head studs will fit by clamping the combination to a bench and using a cylinder head gasket to map the holes that need to be oblonged.

Success! Each of the head studs fit nicely and the head halves meet cleanly. Time for a final mock-up…
