2015-2016 Ford 6.7L Powerstroke Short & Long Blocks

The bottom end of the 2015-2016 Ford 6.7L Powerstroke

The 6.7L Powerstroke is a 90-degree V8 on a compacted graphite iron block, with a 3.897-in bore and a 4.251-in stroke for 405.6 cubic inches. That makes it undersquare, with the stroke longer than the bore. Compression is 16.2:1 and the pistons are aluminum, a combination Ford kept from 2011 through 2019. The complete engine weighs about 990 lb dry and 1,100 lb wet and measures roughly 44.4 in long, 33.3 in wide and 33.7 in tall. Ford rates its B10 life at 500,000 miles on the 330-hp commercial version. More Ford diesel parts are on the Powerstroke hub.

When a short block is the answer

The problems the sources document on 2015-2016 trucks are mostly around the engine, not inside it: fuel dilution of the oil during DPF regeneration, and a sealed CCV oil separator that loads up with use. A short block comes into the picture when the bottom end itself is damaged or worn beyond a refresh, or when you are building an engine for more power and want a fresh foundation. If your block is healthy, the ring sets, thrust washers and gasket kits in our Engine Components collection cover a refresh instead. Whatever is in the truck, the maintenance the sources recommend still applies: 5,000-mile oil changes unless you run oil analysis.

Stock replacement vs. upgrade

If you are replacing with a factory-spec reman or used engine, it needs to be the 2011-2019 spec: 16.2:1 compression with aluminum pistons. A factory 2020 or newer block uses steel pistons, 15.8:1 compression and a different turbo and injection setup, so it is not a match. The other path is an aftermarket short block built for the 6.7L, like the SPE Motorsport OE+ in this collection. An aftermarket block is built to its maker's own spec, so read the build details on the product page and confirm it covers your 2015-2016 before you order.

What we carry

This collection holds the SPE Motorsport S100241 OE+ Short Block, listed for 2011-2023 6.7L Powerstroke engines. Plan the rest of the job around it. Gaskets, seals, ring sets, head hardware, oil and filters for the job are in the other Engine collections for your truck.

Fitment notes

The SPE listing covers 2011-2023, which runs past the 2019 point where Ford's own engine changed, so confirm the build spec suits your engine before ordering. The 2011-2016 chassis cab 6.7L is rated 300 hp and 660 lb-ft with a different turbo, and its turbo and calibration parts are not shared with the 440-hp pickup, so keep your truck's own turbo and calibration parts with the swap. Your 2015-2016 pickup carries the Garrett GT3788V turbo that arrived for 2015, not the earlier DualBoost unit. Verify by VIN, and call us before ordering a block so we can go over the spec with you.

Frequently asked questions

Can I put a 2020 or newer 6.7L short block in my 2015-2016?

Not a factory one. Ford moved to steel pistons and 15.8:1 compression in 2020 and changed the turbo and injection setup, so a factory 2020+ short block is a different part from your 2011-2019 spec engine. Aftermarket short blocks list their own fitment, so check the spec and ask us if anything is unclear.

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

A short block is the bottom end: the block with its rotating assembly. A long block adds the cylinder heads and valvetrain. On the 6.7L the turbo and exhaust manifolds sit in the valley between the heads, so either job involves a lot of top-end disassembly. Line up your gaskets, head hardware and fluids before the engine comes apart.

How long should a 6.7L Powerstroke bottom end last?

Ford rates the 6.7L at a B10 life of 500,000 miles for the 330-hp commercial version, which is a different calibration from the 440-hp pickup. Real-world life depends on duty cycle and maintenance. The sources point to keeping oil changes at 5,000 miles because regeneration thins the oil with fuel.
