Ready Run 6.7L Cummins Engines: Built Right, Ready to Drop In

A start-to-finish engine package for Ram HD owners who want zero guesswork: precision reman long block, BD manifold, BD turbocharger, a complete high-pressure fuel system, and all the small parts that usually hold up installs.

BD Ready Run 6.7L Cummins Engine Package Precision Plus reman long block + BD bolt-ons = a true drop-in Cummins.
Quick Summary: Why Ready Run beats piecemeal rebuilds • What’s inside the long block (CNC blueprinting, ARP 2000 studs, Newen valve job) • Included BD manifold, BD turbo, CP3 & injectors, rails/lines • All ancillary pieces you usually forget • Fitment (’07.5–’12 and ’13–’18) • Install time & warranty • Break-in tips & FAQs.

Why a Ready Run Engine (and Not a Pile of Parts)

Every Cummins refresh starts with good intentions and an ever-growing parts list. Machine shop timelines, back-ordered fuel lines, an actuator that needs calibrating—one missing piece can stall a whole bay. A Ready Run package removes the unknowns. You get a fully re-machined and clean-room assembled long block, already paired with a BD two-piece manifold, a calibrated BD HE300-family turbocharger, and a complete, Bosch-bench-tested high-pressure fuel system from CP3 to injectors—plus the rails, lines, sensors, water pump, thermostat, and even the upgraded Killer Grid Heater installed. The result: fewer vendor calls, less contamination risk, and a truck that fires, idles clean, and goes to work.

Inside the Long Block: Blueprinted, Measured, Verified

Block & Bottom End

  • Disassembled, crack-checked, blasted; all threads tapped and cleaned
  • CNC blueprinting: bore, hone, and deck to spec; crank inspected for size/straightness and repaired as needed
  • Clearances verified: bearings, piston-to-wall, piston protrusion, deck and hone finishes

Cylinder Head & Fastening

  • Head disassembled, crack-checked, pressure-tested
  • Newen precision multi-angle valve job; heavy-duty valve seats installed
  • ARP 2000 studs on every long block for a reliable head-to-block seal

Assembly happens in a controlled clean room, minimizing debris that can compromise fresh rings, bearings, or injectors during first start.

The BD Bolt-Ons You’d Choose Anyway—Already On It

  • BD Two-Piece Manifold (high silicon ductile iron): handles regeneration heat cycles, lowers drive pressure; pre-drilled EGT port. Includes grade 10.9 hardware and spacers. SEMA Cert SC-BDD01-0155.
  • BD Turbocharger (HE300 family): actuator pre-programmed for drop-in install, fully remanufactured and VSR high-speed balanced for long-term reliability and smooth spool.
  • BD High-Pressure Fuel System: Bosch-trained technicians reman the CP3 with a new metering unit; injectors and pump are validated on a Bosch 815 bench to confirm delivery and return rates across conditions. Includes new rails, high-pressure lines, and injector feed tubes for a clean slate.
  • Ancillaries: turbo oil feed & drain, new water pump & thermostat, coolant and oil temp sensors, Fluidampr harmonic balancer, EGR gaskets, oil pressure sensor, grid heater upgraded with BD Killer Grid Heater, dipstick & tube.

What’s in the Crate (So You’re Not Chasing Small Parts)

  • Precision Plus reman long block (ARP 2000 studs installed)
  • BD two-piece manifold (hardware & spacers)
  • BD turbocharger with programmed actuator (VSR balanced)
  • Reman CP3 with new metering unit + reman injectors (bench-tested)
  • New Bosch fuel rail w/ pressure sensor & relief valve; new high-pressure lines and injector feed tubes
  • Turbo oil feed line & drain tube, EGR gaskets
  • New water pump & thermostat; new coolant temp and oil pressure sensors
  • Fluidampr harmonic balancer
  • BD Killer Grid Heater upgrade pre-installed
  • Dipstick and tube

Fitment & Options

2007.5–2012 Ram 2500/3500

Great for earlier 6.7L trucks that need a true reset—fuel system, turbo, manifold, and ancillaries all together.

Ready Run Engine Package ’07.5–’12

2013–2018 Ram 2500/3500

Updated chassis years with emissions-era heat cycles—this package is spec’d to live there.

Ready Run Engine Package ’13–’18

Install Time, Break-In & Warranty

  • Install Time: ~14 hours 30 minutes (typical shop schedule; verify accessories and chassis-specific items ahead of time).
  • Warranty: 24-Month / 100,000-Mile Parts coverage.

Break-In Tips

  • Prime oil & fuel systems before first crank; verify no leaks at rails/lines and turbo feed.
  • Initial fire: let it idle to full operating temperature; vary RPM lightly—avoid extended idle on the very first hour.
  • First 500 miles: moderate load/varied RPM; keep EGTs conservative and avoid long WOT pulls.
  • Early service: change oil & filter after initial break-in window; re-torque external fasteners as required by the install guide.

Frequently Asked Questions

Is the actuator already calibrated?
Yes—BD turbo actuators are pre-programmed for drop-in function. No separate dealer programming required for the turbo itself.

Why include new rails and lines?
High-pressure fuel systems hate contamination. Fresh rails, lines, and injector tubes eliminate carry-over debris from a failed engine and ensure consistent, leak-free pressure.

Do I need to reuse anything from my old engine?
Accessories (alternator, A/C, brackets), intake/exhaust plumbing, and chassis-specific sensors may transfer. The core package covers the engine system pieces that most often delay installs.

What about emissions equipment?
Packages retain OE emissions strategies. The BD manifold and turbo are designed to live with regeneration heat and backpressure—exactly where work trucks live.

Notes: Always follow the included installation and torque procedures. Validate cooling, charge-air, and exhaust connections after first heat cycle. If your previous engine failed catastrophically, flush or replace the oil cooler and thoroughly clean the charge-air cooler to prevent debris ingestion.
