Pump Gas Nailhead Build Takes Innovative Engineering Skill
The nailhead has more in common with a pair of four-cylinder engines than a V8. Like a four, the nailhead is a torquey motor, making all its torque at idle and then, as the rpms go up, the torque goes down and the horsepower rises. Engine builder Guy Henson recently did a custom, high-tech build

Vintage Engines, Modern Results
His business card provides the data on “George’s Speed Shop Precision Racing Engines,” but doesn’t provide much of a clue of who George is or what he does. You might be surprised to learn that the George in this case is better known as “Ohio George” Montgomery, a legendary NHRA national driver. But if you
2011 Stroker Engine Guide: Unlocking LS Stroker Engine Potential
Modifying the LS for more power is as easy as falling off a log, to apoint, then some tough issues arise, especially if you are building ahigh-rpm race engine. But until you reach that point, the LS respondsnicely to boring and stroking, improved cylinder head flow and theyrespond especially well to power adders. The only
Build With Bolt-On Horsepower, But Proceed With Caution
Whether the speed equipment is old school hardware or electronic in nature, you can be sure it is designed to turn automobile engines into more efficient air pumps. “Because the engine really is an air pump, I tell my customers one of the biggest things they can do is bolt on a different exhaust system,”
Inside Flat Tappet Camshaft and?Lifter Technology
Roller cams have a couple of advantages over traditional flat tappet camshafts: they reduce friction, and they can be ground with more aggressive cam lobe profiles to make more power. You can also swap roller cams without having to replace the lifters. But the roller cam’s main disadvantage compared to flat tappet cams is its
Valves, Guides and Seat Materials and Selection
Ginsu knives became a household name by blasting infomercials showing how their superior steel blades could cut through a shoe and then slice a tomato paper-thin. The blades would bend and flex and never lose their sharpness. Millions of homeowners bought the knives; however, you would be hard-pressed to find an executive chef who used
Pro Stock Engine Technology
For a gearhead it’s always interesting to look at the upper echelons of motorsports to see what’s ticking under the hood. F1, Sprint Cup, and endurance cars are all fairly engaging from an engine perspective, but nothing tops drag racing for its sheer power, variety and ingenuity. In a single event you have vehicles competing
Performance Lifters, Pushrods and Valve Springs
Low friction roller lifters replaced flat tappet lifters many years ago in stock production engines, but there are still plenty of hot flat tappet cams bumping the valves open in vintage muscle cars, street rods and race cars. Even NASCAR is still using flat tappet cams to actuate the valves. The advantage of flat tappet

Exhausting Emissions Questions
It’s kind of funny because 20 years ago, no one wanted a clacking bucket of bolts, let alone have to work on one of these diesel engines. That was simply how the diesel engine was viewed. Now, mid-size trucks offer reliable power, awesome torque, quiet engines and decent fuel economy from a vehicle that can

Evolving Crankshaft Designs and Applications
In the early days, a crank didn’t have to be very sophisticated or strong because most engines were an inline design, and the loads and speeds were relatively low. Fast forward to today. The evolution in engine technology, power and performance has led to a whole new generation of performance crankshafts that are a mechanical
How Piston Rings Affect Horsepower
The rings seal the pistons to prevent air and oil from being drawn past the rings into the combustion chamber during the intake stroke. During the compression stroke, the rings make sure the air/fuel stays in the combustion chamber and is fully compressed before it is ignited. During the power stroke, the rings prevent pressure
