Stroker Engine Kits
For more than 50 years the old saying “There’s no substitute for cubic inches” has been the credo of nearly every racer and hot rodder. Whoever created this unwritten universal law could never have imagined to what extremes today’s speed enthusiasts would take it. Now, unless you have a 420cid-plus small-block or a 550cid-plus big-block

Engine Builders: Pistons and Rings – Hypereutectic, Valve, Installation
Though pistons can often be salvaged when remanufacturing an engine, sometimes they have to be replaced. The original pistons may have worn or damaged ring grooves, wrist pins or skirts, or they may have cracks. New pistons may also be necessary if the cylinders have too much taper wear and the block has to be
Understanding High Performance Valvetrain Technology
Parts are getting lighter, stronger and capable of producing more horsepower than ever before. One of the driving forces behind these advances has been the proliferation of aftermarket cylinder heads that require unique valvetrain components. In addition, new computer-aided design, modeling and manufacturing techniques are making it easier and faster for valvetrain component suppliers to

Aluminum Cleaning & Machining
Steel may still be the big dog when it comes to the content of the world’s motor vehicles, but aluminum usage in cars and trucks continues to increase. Fueled by the desire to save weight, time and energy, aluminum is gaining ground with manufacturers of parts and components. How does the use of aluminum in
Heat Treating Processes
Heat-treating is defined as the controlled heating and cooling of a metal in order to change its physical and mechanical properties without changing its shape. A material often hardens or changes characteristics as a result of some sort of process that has been performed, such as machining or welding and is therefore an unintended consequence
Shop Line
We’ve had customer complaints about recurring MILs (malfunctioning indicator light) on some Chrysler 3.2 and 3.5L engines. Any idea what’s going on?

Crack Detection
Take a look in the mirror. Smiling back at you, you’ll notice that row of pearly whites. They probably look pretty good. Maybe a bit stained from coffee or smoking, but overall, they seem to be pretty solid, right? If you’re like many people, the fear sets in as soon as you sit down in
Tech Notes
Engine Builders: As engine technology advances to produce more efficient engines, motor oil must continue to meet the increasing demands for lubricating these precision-made engines. Development of the next specification of gasoline-fuel (GF) motor oil began only months after the latest specification, GF-4, became available in 2004. The GF-5 motor oil specification created by the

Line Boring Equipment: A Boring Subject?
But as the British philosopher Bertrand Russell noted, "Change is one thing; progress is another." While some might say the basic techniques for line boring main and cam bearing bores in engine blocks hasn’t changed much in 30 years others say that isn’t such a bad thing. A horizontal boring bar with cutters mounted on
Pistons and Pins: What’s New
Asking piston manufacturers “what’s new” reveals a number of trends that are reshaping the piston business today. One is that there’s no longer a time lag of three or four years for aftermarket piston suppliers to tool up for the latest piston applications. Production engine remanufacturers (PERs) and custom engine rebuilders (CERs) are asking for

Engine Bearings and Crankshafts, What makes them [not] tick?
The relationship between the crankshaft and main bearings is an integral one. Any metal-to-metal contact can have catastrophic results, and if the carnage was the result of improper finish or fitment, you’ll likely get to work on your relationship skills again.
