Built to Work. Built to Take More.

The Far From Stock Workhorse 12-Valve Cummins is the P-pump build for guys who want real power on tap and a bottom end that can handle where they're headed next.

Studded heads, heavier valve springs, and a P7100 mechanical injection pump make this a platform capable of supporting up to 600 HP. It's the classic 12-valve simplicity you already trust, built with the hardware to back up a serious build.

Tow with it. Drive it every day. Or keep turning it up. The Workhorse is built to handle what you throw at it.

$2,500 Refundable Core Charge

A $2,500 core charge is added to every engine and credited back when you return a qualifying core.

Your engine ships secured to bracing built for the return trip. Send your core back on that same bracing within 30 days of receiving your engine. Return shipping is the customer's responsibility.

We inspect every core on arrival:

• Full credit — complete, rebuildable core
• Half credit — slight block or housing damage, or minor parts missing
• No credit — seized, cracked, fire damaged, excessive rust or damage, or returned past 30 days

Before shipping: remove all fittings, drain all fuel and oil, and package so nothing can escape. Carriers refuse packages with fuel or oil residue. We'll issue your RA number and walk you through the return after your order is placed.

Limited Warranty

Every Far From Stock engine is bench tested and video recorded before shipment.

The Workhorse is a Stage 2 build, covered for 90 days against defects in workmanship.

Workmanship coverage only. Failures resulting from increased power output, tuning, or modification are not covered, regardless of when they occur. Racing, sled pulling, dyno abuse, and competition use are excluded.

To keep coverage active:

• Register within 30 days of purchase with a photo of your FFS engine tag
• Install by an FFS-approved technician
• Run FFS-specified break-in oil for the first 300 to 600 miles
• Follow the maintenance schedule and keep records
• Contact FFS before any diagnostic or repair work begins

Full terms and the registration form ship with your engine.

Custom Paint

Your engine doesn't have to look like everyone else's. After you order, a team member will contact you to go over colors and finish options before your engine is completed.

LTL Freight

Freight is not included in the listed price. When your engine is ready, we'll coordinate LTL freight based on your delivery location and invoice it separately.

After You Order

A Far From Stock team member reaches out directly to finalize your build, confirm paint, issue your core RA number, and lock in freight. Nothing ships until you know exactly what's happening.
