For over 22 years now, we have been building and servicing the 6.2L and later the 6.5L diesel engine exclusively.

Our operation has grown substantially in recent years, thanks in large part to our exposure on the modern internet. We have shipped our engines to every one of the 50 states and many overseas.

We employ experienced, and seasoned technicians, who assemble our engines using all new American parts to ensure a dependable, high quality product.

Each engine is thoroughly tested on the dynamometer. Testing confirms proper assembly and allows us to check for oil & coolent leaks. Each and every engine we build must meet performance specifications and pass individual inspection before it is shipped.

All engines are required to pass dyno testing. This is why we do not offer short-block engines. Short-blocks can not be adequately tested on the dyno.

We are proud of our lengthy track record with the GM 6.5 Liter Turbo Diesel engine. We do not take risky shortcuts during the remanufacturing process. The grievous examples below are actually common practice with some "cut-rate" rebuilders.

• We DO NOT weld on cracked cranks, blocks, caps or heads - or any part of our engines. If the parts are cracked, they are thrown away.
• We DO NOT "sleeve" cracked blocks.
• We DO NOT use any Chinese castings or any cheap "White Box" internal engine parts from China!

Our Updated & Improved 6.5 Engine

Now available - Aftermarket version of GM's new updated engines. These engines are assembled using All New redesigned block and heads to address the cracking issues that plagued the original 6.5 GM castings. The design improvements and re-engineering of the new aftermarket castings add durability and virtually eliminate the potential for cracking in both the block and heads.

The iron used in the new block utilizes molybdenum, a metal yielding a 20-25% increase in strength. The new block design also incorporates taller and wider main bearing webs and caps. In addition the head bolt holes in the block deck are strengthened, vastly improving head gasket durability.

In addition, changes in the water jacket design in the heads have addressed the 6.5's overheating problems. The original 6.5 & 6.2 cylinder heads produced by GM were prone to developing small cracks between the valves. Our new redesigned heads have added chromium to the cast-iron to virtually eliminate these cracking issues.

Our new blocks are  NOT from China. We receive these blocks as raw castings and perform our own CNC machining for bore and decking. This process offers us a far superior platform for the engine build-up than the pre-machined aftermarket blocks, These new blocks and heads offer complete parts interchangeability & bolt hole alignment as OEM Blocks. These new engines gain improved durability & longevity with a High Volume / High Pressure oil pump, our exclusive.

With these important improvements, This new 6.5 is among the toughest 6.5L diesel engine available today.

With diesel fuel costs rising, the 6.5 has seen resurgent interest among truck owners who realize that the 6.5 can offer unmatched fuel economy, often in the 18-21 mpg range. This easily bests the newer diesels such as GM's Duramax and Ford's 7.3 6.0 & 6.4 Liter engines.

Available as a long block & as a complete drop-in - see our products and pricing page for more details.

We also offer a 6.5 Marine Diesel engine. This engine is built specifically for Marine applications with an 18:1 ratio.

Our Guarantee Be assured with our Unlimited milage, one year warranty covering every engine we sell. This includes both our New/Improved 6.5 & Our rebuilt 6.5 Diesel engine.  You expect hard work from your diesel powered truck, and we'll guarantee it.

Internal Components

All New and remanufactured engines are CNC machined, including line boring & decking.

Compare to others: Our longblocks come with already installed; valve covers, oil pan, oil pickup tube, timing chain cover, new harmonic balancer.

All long blocks have NEW pistons, connecting rods, valves, valve springs, valve keepers, push rods, rocker arms, lifters, camshaft, timing chain, timing gears, valve guides, three angle seats, cam, rod and main bearings, piston rings, gaskets.

All our engines are upgraded to a High Volume / High Pressure oil pump.

Nobody else has this pump. It's our Exclusive!

The 6.5 TD desperately needs a boost of oil to the main bearings.

 This pump does the job like no other in the business!

All moving parts are NEW, with the only exception being the crankshaft. The crankshafts are magnafluxed and all bearing surfaces are restored. The service life of the crankshaft is effectively restored to like NEW condition after our machining process is complete. Often the results are better than new, considering the personal attention each crankshaft gets in our facility as compared to the mass-output standards at the GM factory. A large percentage (60-80%) of the cranks that come back with the cores are unacceptable for rebuilding, therefore we actually replace a large percentage of cranks with new, however machined cranks and new cranks perform to the same standard.

We use MAHLE Clevite branded internal parts on both our new and remanufactured offerings. These are top quality parts from the same well known industry leader that GM & AM General both continue to buy from.

Core Deposit

There is a $500.00 core deposit that will be refunded when rebuildable core is received back. Any of your core's deficiencies can be pro-rated and may not necessarily mean complete forfeiture of core deposit.

Just let us know when the core is ready, and our freight company will pickup the core. We pay return shipping for core.

Our core deposit is just $500, not $1000 or even $1500!, like some other companies on the internet.

The core charge will be $1000 for international orders, since no core return is feasable due to shipping costs.

Shipping

Shipping is by truck freight and cost is between $260-$450 depending on your location.

($260-$320 In Eastcoast Region , $440 for parts of California, points between vary accordingly)

We can also quote for International shipping Rates.

Please Note: We request that you don't call or e-mail with retrofit or gas to diesel conversion questions. Conversions are generally not worth the effort or cost and entail quite a bit more then someone with limited experience usually thinks.
