Powerhouse Diesel 01-16 GM 6.6L Duramax Short Block

We own the machines that build this engine. Every operation happens under our roof — no outsourced machine shop, no third-party assembler, no waiting in someone else's queue. We control the tolerances, we control the schedule, and when you call about your engine you're talking to the people who actually built it.

Machined and Assembled In-House

• Blueprinted and balanced rotating assembly
• Compstar crankshaft with HX main bearings
• Machine work, assembly and final inspection all performed by our own technicians on our own equipment
• Built to order, so the build sheet reflects your application — not a shelf unit someone else assembled months ago

Complete Gasket Package — Included

Every gasket needed to install this engine comes with it — top and bottom end. Most builders sell you a short block and leave you chasing gasket sets separately. We include the full engine gasket package in the price.

What's Included

• Compstar crankshaft
• Stock camshaft
• HX main bearings
• Top and bottom end gasket sets

Fitment

2001-2016 GM 6.6L Duramax — LB7, LLY, LBZ, LMM and LML.

Core Charge

This engine carries a $2,500 core charge. If the rods or crank are not good, you will be credited for whatever is good.

A core is automatically considered bad if:

• There are holes in the block, or the engine will not rotate over
• Any holes have to be sleeved

Available Add-Ons

Because the machining is ours, so are the upgrades — we can build this engine to your spec rather than sell you a fixed package:

Pinned Wagler oil pump · alternate firing Callies cam · valve springs · pushrods · piston coating and valve reliefs · Wagler or Carrillo rods · Stage 1/2/3/4 cams · ARP head studs, main studs and other fasteners · aluminum heads · O-ringed heads · ported heads · upgraded lifters · O-ringed blocks.
