Fueling the Future – Can You Fill Up with Alternative Fuels?
Currently gas prices have stabilized at around $1.83 a gallon, a price at which most Americans feel comfortable driving their SUVs, trucks, race cars, tow vehicles and other motorized toys. But when gas hits $4 and $5 a gallon, driving guzzlers becomes a challenge for many. It was only a few months ago that a
Harvesting Profits From the Farm/Agricultural Market
When we last visited the subject of the opportunities in the agricultural market, (Engine Builder, March 2006) we discussed the diversity that may not have been apparent to everyone. While many would immediately think about tractors, combines and maybe, grain trucks, most would not have realized that the farm and agriculture industries are much more
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.
Building a Hemi 528 Stroker Engine
The Hemi has made a comeback in recent years in various Chrysler and Dodge vehicles, most notably in the Charger and Challenger. But for hardcore Hemi fans, the real deal goes back to the first-generation 331/354/392 mills that culminated in the “Elephant Motor,” the 426 Street Hemi of the Sixties and Seventies. Even though the
Understanding Valve Design and Alloys
To the naked eye, a valve is a valve is a valve. Sure, there may be two, three, four or more of them in the cylinder head, but unless you have x-ray eyes, one alloy looks pretty much the same as another. The importance of coatings to today’s valves should not be overlooked, of course.
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

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
Kicking Asphalt
In this election year it somehow seems appropriate to talk about a movement that reaches the common citizen…the working man…the small-business person. Political rhetoric aside, it has the potential to gain traction in the industry and showcase what’s great about America – grassroots road racing. There are no multi-million dollar sponsorships (multi-million dollar wallets not
