Ford’s Power Stroke Powerplants
The biggest question heard from customers is, “Why did Ford replace the 7.3L with the 6.0L?” There are good reasons as to why the 7.3L Power Stroke had to be removed from service and these reasons brought about many changes in the Power Stroke platform.

Vintage V8s: Exploring 100 Years of Cadillac Engines
For more than a century, the name Cadillac has been synonymous with performance, style and passion. And in those early years of the Cadillac Automobile Company, it was a former loom mechanic – Henry Martyn Leland – who was credited with forging the technologies that separated Cadillac from the other automobile businesses that were springing
Engine Builder Shop Solutions – January 2014
Replacement Head I.D. for Ford 6.0L Diesel Identifying a Ford 6.0L head by dowel size alone does not necessarily get you the correct replacement cylinder head. Ford/International have two casting numbers for their 6.0L head, the early 1843080C1 through C4 heads which all have 18mm dowel holes and use an 8mm mounting bolt for the rocker

Tips for Ford Power Stroke Service and Rebuilds
Bob McDonald, who contributes diesel stock and performance articles for Engine Builder magazine, including the column “Diesel Dialog,” has authored the book “How to Rebuild Ford Power Stroke Diesel Engines 1994-2007.” The book covers the vast majority of Power Stroke diesel engines on the road, and gives you the full story on their design. A
What’s Under the Bun of the Wienermobile
Most of the Wienermobiles you see on the road today are powered with a Vortec V8, 6.0L, 300 hp engine. “Oh, I wish I were an Oscar Mayer Wiener, that is what I’d truly like to be…” I’ll stop there because I know how easy it is to get that catchy tune stuck in your
Venturing Into GM Duramax Diesel Service
There are five generations of the Duramax engine. The best way to identify the generation is by the year, model and the RPO (regular production option) code. Back in the 1990s, GM wasn’t making too many waves in the diesel truck market. The 6.2L and 6.5L engines had been around for sometime, but they were no match
Diesel Exhaust Fluid Not So Bad
I often hear comments from people about a strange and mysterious fluid called DEF (Diesel Exhaust Fluid) that is used in some late-model diesel trucks. Many owners of these newer diesel-powered vehicles don’t know what DEF is or why they have a separate tank or even how often to add the stuff. And what exactly
Oiling System Technology
Oil is the lifeblood of every engine. Any significant loss of oil pressure can destroy an engine in a split second so the oiling system must provide a constant supply of oil under all operating conditions. With performance engines, keeping the engine lubed with a steady supply of oil can be a challenge because
Holley Performance Announces its Participation in the 2013 Hot Rod Power Tour
While Holley’s display trailer will be present at every stop, its most exciting stop will be the Holley sponsored checkpoint at Birmingham, AL, on Wednesday, June 5, 2013. Throughout the day in Birmingham, Holley and Mothers Polish will be sponsoring an autocross in the parking lot of Hoover Metropolitan Stadium (only open to registered
‘Heads Up’ On Today’s Cylinder Heads & Bolts
Some say the air cleaner of an engine is like the front door of a house. That is, it’s what you see first and foremost. And the home owner can use that door to make a statement about the house without anyone seeing what’s inside. Much like what an air cleaner says about an engine
Technical Information on Rebuilding GM LS Engines
The Issue: When the OE composite designed cylinder head gasket changed to an improved Multi-Layered Steel (MLS) design for the 4.8L & 5.3L in 2001 and 6.0L in 2002, the cylinder head gaskets were no longer interchangeable. This prevents engine builders and technicians from installing the best MLS designs in older engines of the GM
Robert Yates, Sunnen, Team Up For 2012
After working hard for three days to build a 600 hp and 495 ft-lbs. NASCAR-approved spec engine valued at more than $28,500 legendary engine builder Robert Yates offered apologies that only one person could take the engine home from the recent IMIS Show. Nancy Plagman of Wizmo, Inc., in Bloomington, MN, held the winning ticket,
Racing Rocker Arm Technology
The rocker arms play a more important role than ever these days in high performance valvetrains. The rockers are the teeter-totters that translate the upward motion of the lifters and pushrods to the downward motion that opens the valves. It seems like a relatively simple task, but it demands the utmost from the design of
Takin
Back in the old days, the late ’90s, when the economy was strong and incomes were high, people had a lot more money to put toward their favorite hobby, which for many was a souped up car that could be driven on the street but maybe also a little on the track as well. Today,
What
That’s why you have to choose the gaskets you install very carefully. Gaskets have to fit correctly and have the durability to maintain a long lasting seal. Applications that are unusually demanding often require specially engineered gaskets that can handle higher pressures and temperatures without failing. Advancements are constantly being made in gasket materials and

Pump Gas Nailhead Build Takes Innovative Engineering Skill
The nailhead has more in common with a pair of four-cylinder engines than a V8. Like a four, the nailhead is a torquey motor, making all its torque at idle and then, as the rpms go up, the torque goes down and the horsepower rises. Engine builder Guy Henson recently did a custom, high-tech build
