We also have the block for Centermount Turbo applications, (Turbo H-1 Hummers, Grummin Box trucks, Vans & some RV's)

This is a top quality New & Improved 6.5 Block Casting

We realize this is not the absolute cheapest block on Ebay, however we believe once you know all the facts and details about our block and the shortcomings of the other offerings on Ebay and elsewhere online, you will agree, this block is worth paying a little more for than a cheap Chinese knock-off.


For over 21 years now, we have been involved with the  6.2L and later the 6.5L engine exclusively, we don't use or sell any Asian sourced parts.


If a seller/retailer does not state in their ads where their blocks are made, you can believe the country of origin is not exactly a selling point for them. One tip-off  is to look at the core plugs, are they quality brass? or are they cheap, rust-prone steel? 

Call or email sellers and ask, if you really want to know.


Compare to others: These blocks are cast and machined in Brazil (just like OEM) by experienced, well-paid, real machinists. Other companies offer new blocks, but be careful, most are using the old casting forms, and no improvements to the metallurgy - AND ARE USUALLY FROM CHINA.  There are only a handful of others in the USA offering truly IMPROVED & UPDATED castings, aside from AM General and General Motors themselves, and they are selling for considerably more than we are.


Beautiful smooth-honed cross-hatched cylinder bores, ready to properly seat your new rings.
Premium cam bearings come already installed.

1/2" pipe threads for the oil cooler lines, to accommodate the new high pressure / high volume oil pumps.

New threaded plugs and new cam plug included with every block.

New Main cap bolts, installed, 4 per cap, Two, different, distinctly designed bolts, (inner & outer).

This is the block used by many major professional builders / rebuilders of the 6.5 Diesel here in the US, as well as the US Marine Corps.



Rebuilding your 6.5 is a major investment of your time and money, start with a solid foundation worthy of your efforts.


As many of our customers already know, the original 6.5 castings were plagued with cracking issues.

The design improvements and re-engineering of these new castings add durability and remarkably diminish the potential for block cracking,....... like none to date.  

The iron/alloy used in the new block utilizes molybdenum, a metal yielding a 20-25% increase in strength. This increase in strength comes without the brittle characteristics of nickel, used in high concentrations in the OEM castings until 2002.

The new block design also incorporates improved main bearing webs and caps.

In addition, the head bolt holes in the block deck are strengthened, vastly improving head gasket durability.

Complete parts interchangeability & external bolt hole locations as OEM Blocks, everything bolts right up!

We have been selling the improved version 6.5L block for almost 4 years now with great over-the road success, Not one block cracking issue to date. - Now that's what we mean by an improvement.

Be assured with our Unlimited Mileage, one year warranty covering every block we sell. You expect hard work from your diesel powered truck, and we'll guarantee it.

Shipping is by Insured truck-freight, set at a flat rate of $160, anywhere in the lower 48 states, USA.

Listed International rates are estimates and will require pickup at closest available air or seaport.

Call our internet sales department at 828-453-7779 prior to ordering to insure we order the correct block for your specific application and to give you your exact total, including proper freight quote, (if International). We can discuss your engine questions and options over the phone more efficiently than email.

You will need to be able to unload your shipment from a semi-truck at a commercial address. Residential delivery/liftgate service costs about $100 more.
