The Shermanator 347: A 530HP Gas Stroker You Can Build
A while ago Engine Builder ran a story on the popularity and basic dos and don’ts of stroker engines ( March 2007 Engine Builder). It received such great response that we are following up with a “real world” stroker engine buildup. In this case, it is an engine combination that is so popular that it
The Ups And Downs Of Valves
It’s always good to take a fresh look at some of the many engine components we work with. Rather than being lulled into complacency, the idea is to see what’s new, what trends are in play and to get a current reading from others on the inside. In other words, it’s good to keep it
Resurfacing Cylinder Heads & Blocks? Mistakes to Avoid
Cylinder heads and blocks may need to be resurfaced to restore flatness or to improve the surface finish, or milled to change the deck height for a variety of reasons. The deck surface on the head or block may need to be resurfaced if the surface isn’t smooth or flat. A head may need to
Dialing in on Today’s Engine Bearing Trends
Durability is less of a concern today because the aftermarket and OEMs demand bearings that can last 150,000 miles even under severe stress from a neglectful vehicle owner. In performance applications there are a number of materials that will do the job well. Each material has its advantages in terms of resistance to corrosion, rate
Engine Sealing Lowdown
With engines now lasting as long as 150,000-plus miles, there’s little doubt that the OEMs have created a monster! Gasket technology advances have played a significant part in the longevity and durability of today’s engines. They must be robust and durable enough to withstand a hostile environment for such a long life, and without leading
Rocker Arm- Form & Function
For all the changes in the performance engine over the years, one constant remains – no matter what series they’re running, no matter what the payout, no matter if it’s just a couple of guys trying to outdo each other stoplight to stoplight, racers will often spend money they don’t have in search of the
Drag Racing Crankshafts
With photos and words by Steve TempleAs any experienced engine builder already knows, a drag race engine is made up of hundreds of precision parts bolted together to form an assembly that spins at a furious rate in order to propel its vehicle to victory. Meeting this challenge requires that all those parts going into
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
Blasting Equipment & Media
In today’s society, finding “the next big thing” seems to be all the rage. We no longer want to do things the same way and seem to keep asking “what’s the latest and greatest?” High technology and computerization have made many tedious everyday tasks a breeze, from communication to entertaining to operating your business. But
AETC Review
The 17th Annual Advanced Engine Technology Conference (AETC) was held for the second year in a row at the Orlando Convention Center, Dec. 11-13, just days before the opening of PRI. While the weather wasn’t frightful, there wasn’t quite as much Florida sunshine as the previous year either, but the talk around each morning’s breakfast
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
Over the Peaks and Into the Valleys – Hones, Diamonds and Bores
“Your mission, should you choose to accept it, is to find the recipe for perfect bores…your instructions are to produce bores that are perfectly straight and round. This message will self-destruct after five minutes. Good luck.” Although it’s not “Mission: Impossible,” good bore geometry is critical in order to achieve proper ring sealing. Bore distortion
Old Iron, To Satisfy Vintage Engine Buyers, Go The Extra Mile
Here’s the scene: You’ve just completed the machine work and assembly of a fine vintage engine. It may be for a restoration or a hot rod or a custom. You may have rattle-canned the block and heads and maybe wrapped it up in a baggie. To you, knowing that function is primary, the job is
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
Engine Parts ETs Drop From Inspiration to Installation
It’s a simple process for those down in the trenches. An engine builder will make a phone call or click on a computer and within days, the latest parts show up at his shop, ready to be installed. But the traditional Stork method of delivery notwithstanding, exactly where do new engine parts actually come from?
Performance Valves
The power that an engine produces depends to a large extent on how much air it flows. The larger the engine’s displacement in cubic inches, the more air it pumps with every stroke and the more horsepower it makes. Rpms also make power. In theory, doubling the engine’s speed doubles its power output. Rev an
Diesel Drag Racing, Compression Ignition Engines Smoke The Strip
It is one of the purest forms of American motorsports. One guy pulls up next to another guy at the starting line and revs the engine. A simple glance over, a nod and a green light. In a fury of sound and smoke, the two racers take off down the straight stretch of pavement. If
Marine Engine Building, Is It For You?
Engine builders who do passenger car and light truck engines, diesel engines and performance engines, are often looking for new market niches where they can expand their business and add new customers. For some, marine engine building may seem like a tempting niche. The marine engine market is relatively healthy, though highly competitive. Some rebuilders
Engine Sealing: High Performance Head Gaskets
One thing no engine builder wants to worry about is a head gasket failure, whether it is a NASCAR cup engine, a Pro Stock drag racing engine, a dirt track engine, a hot street engine or even a stock engine. Stock head gaskets hold up well enough under normal loads. But as compression ratios and
Machining Solutions For Compacted Graphite Iron
During the last couple of AERA Shows, a seminar on machining a relatively unknown material called Compacted Graphite Iron (CGI) has drawn an interested and growing crowd. The first year’s seminar was the first many had heard about this material and some may have left wondering if this material was headed to their shops any
