2011-2014 Ford 6.7L Powerstroke Short & Long Blocks

The 2011-2014 6.7L Powerstroke bottom end

The 6.7L Powerstroke is built on a compacted graphite iron, deep-skirt block. Bore is 3.897 inches and stroke is 4.251 inches, compression is 16.2:1 on 2011-2019 engines, and the firing order is 1-3-7-2-6-5-4-8. The engine weighs about 990 pounds dry and about 1,100 pounds wet, and it measures 44.4 inches long, 33.3 wide and 33.7 tall. Ford designed it around a 500,000-mile B10 life, so a healthy bottom end is expected to go a long way. The failures that put a new block on the table are the early 2011 problems below.

When a short block makes sense

Engines built on or before March 29, 2011 had exhaust valves that could break off and destroy the piston, cylinder and head. Some early 2011 engines, mostly reported on chassis cabs, also had two-piece ceramic glow plugs whose tips could drop into a cylinder. Both failures are sudden: loud banging or a knock, an immediate loss of power, often a stall. An event like that typically means a long block. A short block is the bottom end, the block with its rotating assembly, and it is the choice when you are keeping or separately sourcing the heads.

Stock replacement vs. upgrade

SPE Motorsport calls its short block OE+, and it is listed for 2011-2023 6.7L engines. Read the product page for exactly what is included and what SPE changed from the factory parts before you plan the rest of the build. Whatever bottom end you choose, the top-end decisions follow: new head gaskets, a fresh bolt set or a stud kit, and whether your heads go back on or get replaced.

What goes back on with it

Any head going onto a new bottom end should be pressure tested and checked for warpage first; head replacement labor usually costs more than the casting, so you do not want to do it twice. Start the fresh engine with a new CCV separator, because a clogged one raises crankcase pressure and pushes oil past healthy seals. Fill it with 13.0 quarts including the filter, using oil that meets Ford's API CJ-4 and WSS-M2C171-F1 spec. Head studs, gaskets, oil and filters are in the other Engine collections for this truck.

What we carry

The SPE Motorsport S100241 OE+ Short Block, listed for 2011-2023 6.7L Powerstroke engines. Talk to us before ordering; a short block is a big decision, and we install what we sell.

Fitment notes

Verify by VIN, and tell us whether the truck is a pickup or an F-350, F-450 or F-550 chassis cab, since chassis cabs run a different turbo and a 300 hp, 660 lb-ft calibration. If you are rebuilding an early 2011, the lower oil pan and some fittings are 2011-only, so plan those parts before the engine goes in.

Frequently asked questions

What is the difference between a short block and a long block?

A short block is the bottom end: the block and its rotating assembly. A long block adds the cylinder heads and valvetrain. On this engine, a catastrophic early 2011 valve failure typically calls for a long block, because a dropped valve can destroy the piston, cylinder and head together.

Does a broken exhaust valve mean my 2011 6.7L needs a new engine?

It typically means a long block. A broken exhaust valve can take out the piston, the cylinder and the head at once. Have the engine inspected; if you go the short block route, the heads you put back on must pass a pressure test and a warpage check.

Will the SPE OE+ short block fit my 2011-2014 truck?

It is listed for 2011-2023 6.7L Powerstroke engines, which covers this range. Confirm by VIN before ordering, and call us with your details if the truck is a chassis cab or has an early 2011 build date.
