For a gearhead it’s always interesting to look at the upper echelons of motorsports to see what’s ticking under the hood. F1, Sprint Cup, and endurance cars are all fairly engaging from an engine perspective, but nothing tops drag racing for its sheer power, variety and ingenuity.

Engine Builder Shop Solutions: January 2011
Keeping Gaskets In Their Place Can’t get a hard to reach gasket to stay in place even using various types of sealers? Try this trick that worked for me.

Post-War Engines: The Greatest Generation?
“The popularity of the post-war engines being rebuilt is not much different than the pre-war models,” says Packard Industries’ Bob Rovegno. “GM rules the roost, with Cadillac, Oldsmobile, Buick leading the way, and surprisingly, Lincoln-based 383s, 410s, 430s, 462s are next and the old Mopar or Ford flathead V8s are up there in the top

Dynos and Test Stands: Profit Center or Business Black Hole?
Dynamometers allow an engine builder to test, tune and tweak his engines before giving customers the opportunity to do something foolish with them. In a recent poll on Engine Builder’s website, we asked our readers how important a dyno is to their business. According to our (admittedly unscientific) results, 44 percent of Engine Builder readers
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. Back in its infancy, I covered weekly bracket racing in Southern California at the now defunct Irwindale and Orange County International Raceways. The action was hot and heavy with full fields of
