Performance Marine – Is It the Last Engine Frontier?
It is said to be one of the last great open frontiers. Many experts say that it’s just about the last place on Earth where there are no rules to confine speed or size. It’s a place that has lured men with adventure and danger for centuries and now may be calling you, the engine
Boosting Performance – Nitrous, Superchargers and Turbochargers
From the budget six-cylinders that get 300 hp and 28 mpg for less than $25,000 to the 600 hp Viper V10 to the 630 hp Corvette ZR1 for just over $100,000, the performance market is deep and wide. “It’s amazing, the horsepower potential that these cars are coming with off the factory floor,” says Frank
Performance Rocker Arm & Shaft Systems – Time-Tested Technology Provides Proven Performance
The SB Chevy ball and stud stamped steel rocker arms were a revolutionary departure from the shaft mounted rocker arm systems of that era because they allowed it to outrev its competitors. More revs means more airflow and more power. It wasn’t until 1962 that Ford finally dumped their old Y-block 312 rocker shaft engine
Understanding The Mysteries Built Into The Ford Power Stroke Engine
After servicing and answering questions about these engines for several years, it finally occurred to me that the owners of these engines didn’t understand how they work – and, frankly, neither did many repair techs. I remember when Ford introduced the Navistar engine in the middle of 1994. The rumor on the block was that
Take Care of Your Tooling and It
Let’s face it, when you invest in new state-of-the-art equipment, some or most of that investment is in the tooling. That tooling needs proper care – especially if you want your new machine to perform according to the manufacturer’s specs. These newer machines don’t have a clue that your tooling is dull, bent, nicked, burred,
Gaskets, Seals, Sealants and Fasteners
The factors that typically cause a gasket to fail include age, heat, thermal expansion, abrasion, pressure, vibration, corrosion, material breakdown or poor design. Some gaskets go the distance and others do not. With head gaskets, problems like detonation and engine overheating can damage the gasket very quickly, causing an otherwise good gasket to crack or
Shifter Kart Engines: Opportunities from Spec to Open Classes
Like many forms of racing in this economy, shifter kart racing is in a state of change. With substantially more power, a six-speed sequential gearbox and 4-wheel brakes, they certainly delivered "bang for your buck" performance. Probably the biggest testament to the value of racing shifter karts is the career path of Scott Speed who
A Winning Pair
The Automotive Parts Rebuilders Association (APRA) and the Automatic Transmission Rebuilders Association (ATRA) will both be holding their annual expositions at the Riviera Hotel and Casino in Las Vegas prior to the AAPEX and SEMA Shows. Combining the two shows – APRA’s The BIG R Show and ATRA’s Powertrain Expo – into one all-encompassing exhibit
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
Building to Race, Racing to Win
Building championship-caliber engines isn’t a new concept to Jeff Williams. Since he started building his first stroker 302 Ford at age 14, the West Texas native/Southern California transplant has been looking for ways to go faster than his competition. These days, that’s often a very challenging assignment. But more on THAT in a minute. “I’ve
Valve Seat Selection and Machining
When rebuilding a cylinder head for a stock automotive application, a performance engine, or a heavy-duty diesel, what kind of replacement seats should you use if the original valve seats need to be replaced? Should you install new seats that are the same as the original seats, or should you use a different type of
Choosing Aftermarket BBC Cylinder Heads for Street/Strip Applications
In 1958, Chevrolet released the first big block for use in its trucks and heavier passenger cars. It was called the “W” engine and it came in three engine displacements until 1965: 348 cid, 409 cid and 427 cid. After Chevy introduced its “mystery engine” to NASCAR in 1962 with a combustion chamber and canted
