Sleeves & Liners
I often hear customers ask about the difference between a sleeve and a liner. It’s an understandable question. Automotive guys call them sleeves and diesel guys call them liners. And while they may be used for similar purposes, the perception of what they do may be very different among different groups. Many automotive enthusiasts understand
Livin
One of the only ways you can prove your worth as a race engine builder – besides on the racetrack, of course – is on a dynamometer. Being a shop without a dyno may be akin to running blindfolded: you can surely build a good engine, even a winning engine, but you probably won’t know
Crank It Up
Whether you think diesel crankshafts are the same as or different from their smaller gasoline counterparts, you’re right. Diesel crankshafts and rotating assemblies – like their cousins in the gas engine world – turn a linear motion from combustion into a rotating motion that can move a vehicle, supply power through a generator, pump oil
Automotive-Powered Inboard Hydroplanes
They’re fast, have power aplenty, can turn on a dime, and throw a huge column of water behind them. They’re called Inboard Hydroplanes and are one of the most exciting motorsports shows on water with their automotive powerplants.

Racing Rocker Arm Technology
The rocker arms play a more important role than ever these days in high performance valvetrains. The rockers are the teeter-totters that translate the upward motion of the lifters and pushrods to the downward motion that opens the valves. It seems like a relatively simple task, but it demands the utmost from the design of
Dry Sump Oiling Systems
Dry sump oil systems are used on all kinds of racing applications from NASCAR, circle track, road course and Formula One racing to ProStock drag racing. Dry sump oil systems are even found in some current production applications such as the LS9, LS7 and LS3 engines in late model Corvette ZR1, ZO6 and Grand Sport
Engine Blueprinting Basics
The top professional divisions in racing today for the most part run engines that are built to comply with a very strict set of rules for each series. In NASCAR, where the engines have been roughly the same 358 cid V8 for decades, the power output has steadily increased. Engines of the same brand that
Camshaft Selection
When it comes to racing, sometimes the belief is that only custom-designed parts are good enough for a winning team. The question here is, do off-the-shelf components automatically have a performance handicap? In order to get to the bottom of the “Custom Grinds vs Catalog Specs” debate Engine Builder magazine reached out to experts at
Building A Top Class 565 Engine
What does it take to put a top-notch Sportsman drag racing engine in the winner’s bracket? Obviously, parts selection, assembly expertise and a talented driver are key. Over the years, Engine Builder has been an advocate of mastering the first two – the last one is always a gamble. But in some cases for that
Chevy
When the all-new 2014 Chevrolet Corvette arrives late next year, it will be powered by a technologically advanced 6.2L V8 that delivers an estimated 450 horsepower and runs 0-60 mph in less than four seconds.

Butterfield, Bubba and Me
Okay, so saying?“I have to play golf when I’m at the PERA?Annual Convention” doesn’t sound like the toughest way to spend an afternoon. But when you’re A; not much of a golfer (me), B; teamed with some industry bigwigs (Peter Butterfield of LKQ, Ken Carter of MAHLE?Clevite and Robert?Yarbrough of Bishop International) and C; expected
