Scoping Out the Sport Compact Market
At first it was known as the Import Tuner Market which later morphed into what is currently known as Sport Compact. However, the market could be changing again and may soon be called something else. Last year, the Specialty Equipment Market Association (SEMA) changed the name of its Sport Compact Council to Street Performance Council
Crankshafts and Bearings for Street Performance and Racing
Most engine builders have strong opinions and brand preferences when it comes to choosing a crankshaft and bearing combination for a performance engine application. Their preferences (and prejudices) are usually based on years of experience, both good and bad. Many subscribe to the philosophy that “if it isn’t broke, don’t fix it!” Consequently, if they
Cleaning: Different Methods for Different Needs
Back in the late 1800s, the director of the U.S. Patent Office was said to remark “Everything that can be invented has been invented.” Charles Duell, U.S. Patent Commissioner in 1899 reportedly told the President of the United States that there was no more innovation and, therefore, no more need for the patent office. Except
A Winning Pair

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
Rebuilding the CAT 3208 Diesel
Since information from Caterpillar is always held very tight within the family it was very hard to get an accurate history of how the relationship all came about, so if I’m a bit off in my timeline, forgive me. I assure you, it won’t affect the content of this article. The bottom line is, Ford

EFI Introduction 101
EFI has become the tool that has unlocked the next level of engine performance. Nowhere is it more evident than in drag racing, where EFI has taken over where the rules permit. Take Joe Dunn’s Pat Musi-powered ’68 Camaro that just rocked the competition with a 6.38 @ 218 mph pass. Its 755 cid big-block
Selecting Cranks, Rods and Bearings For Your Next Build
Racing engines are made for one thing – speed. But speed is a wide target. It is in the sum of parts that are bolted together to make up the package that speed is delivered to your customer. Engine builders know that one of the biggest areas where races are won and lost is in
Valve Seats & Machining Guide
Engine cooling doesn’t only happen at at the radiator. The valves (particularly the exhaust valves) take a lot of heat from the combustion chamber and the valve seats have the responsibility of helping to cool them off. The seats draw heat away from the valves and conduct it into the cylinder head, providing most of
Manufacturer Tech Tip: Matching the Proper Rings to the Piston
Over the years there have been many changes made to the profile of piston rings. Examples of the most common changes have been from the rectangular to a keystone design, ring materials, and changes to the profile of the ring face. In this bulletin we discuss the changes to the width of the rings. This
What’s Rockin’ In Performance Rocker Arms and Valve Springs
Horsepower is in the heads. But for a cylinder head to breathe efficiently, the valvetrain must be rigid and strong to minimize flex, but also lightweight. For most performance applications, that means replacing the stock rocker arms, valve springs and pushrods with some type of aftermarket roller rocker arms, stiffer valve springs and stronger pushrods.
Takin’ it to the Streets: Performance Valvetrains for [almost] Everyday Use
Even though the valvetain plays a supporting role in the overall performance potential of an engine it can still be a make or – frequently – break proposition for engine builders. In a street performance application in particular your customers are usually quite proud of their vehicles and spend a lot of money on appearance.
Hot Topics: In-House Head Welding Repairs Increase Profitability, Productivity

Here’s a look at how you can potentially increase profitability and productivity by bringing it in house. Doing these kinds of welds successfully requires
Oil Pumps
It’s 6,000 rpm – do you know what your oil pressure is? That’s a question every engine builder should know the answer to if they’re building an engine that’s going to survive. Maintaining adequate oil pressure and volume is absolutely essential for engine durability. The problem is the output of many stock oil pumps, particularly

Head and Block Surfacing Equipment Update
How smooth is smooth enough? You used to be able to tell by dragging your fingernail across the surface of a cylinder head or engine block. And besides, it didn’t really matter because the composite head gasket would fill any gaps that your equipment or technique left behind. But with MLS gaskets the requirements have
The Inside Angle on Valve Seats: What you need to know to go with the flow
No one knows airflow better than the legendary Joe Mondello, who rose to fame back in the 1960s for his race-winning cylinder head work. “Back in those days, we didn’t have flow benches to test our work. Our test bench was the drag strip. If a modification worked and made the car run faster, that’s
