Rebuilding The 6.6L Duramax Diesel
It was really no surprise, since GM had single-handedly alienated the American buying public against the diesel engine beginning back in the late ’70s and early ’80s with the 5.7L V8 and 4.3L V6 diesel engines that were, let’s just say, “less than stellar.” While there’s no point now in rehashing mistakes of the past,

Engine Builder Shop Solutions: June 2010
Cover the Deck When honing cylinders in an engine block use duct tape to cover the deck. Then take a sharp razor knife and carefully trim out the cylinder bores.

A Closer Look at BBC Bracket Racing Cylinder Heads
However, it proved to be just the opposite – sportsman racers loved it and it allowed local drag racing to thrive and grow.

Building a Late Model Hemi Stroker
What is the purpose of stroking a motor? The answer is simple: to obtain more cubic inches. And in today’s economic times, it’s always best to achieve “more” with less – as in less money.

Caburetors and Electronic Fuel Injection Systems
These days just about everyone is looking to new technology to solve their problems. In some cases it makes sense: others, not so much. Take the trusty old carburetor for example: it has been around since the beginning of time (automotive time anyway), and many have predicted its demise, but somehow it keeps coming back
Street Performance Cylinder Heads
Where I grew up in Connecticut wasn’t the hotbed of street racing like Woodward was in Detroit, but we had the Berlin Turnpike, River Road in Middletown, plus a few local small-town hotspots. It was during this period that I got my first education about the importance of cylinder heads. A local rich kid got

Mysterious Processes, Proven Results
While cryogenics – the technology for producing and using cold in a variety of ways – saw significant achievements in technology and applications in the latter half of the twentieth century?(and continuing, of course, today), scientists have been developing ways to make things colder and colder since the late 1800s. The successful process of liquifying
