Install the camshaft and locate plate in the
Which Cranksfaft Meets Your Racing Needs Best?
There are a lot of racing crankshafts in the automotive aftermarket today. You’ll find a wide variety of styles, strokes, weights and price ranges from which you can choose. The question you need to be asking is which crank is “right” for the engine you’re building? The answer to that question depends on several things
Heavy Duty Diesel Rebuilding Opportunities
It’s certainly no secret that the engine rebuilding industry has been hurt by better quality, longer-lasting automobile engines. The same thing – but taken to an even greater extreme – can be said about the heavy duty diesel engine market. “The quality of today’s engines – both automotive and diesel – is so much better
Aqueous Cleaning Systems Offer Economical, Ecological Benefits
As concern for the environment and worker safety has increased over the years, attention paid to the cleaning processes used in engine rebuilding facilities has sharpened as well. No matter what size the shop, engine components are dirty and need to be cleaned. There are numerous ways to clean parts, of course, and no method
Cylinder Head Crack Repairs
It seems as if many cylinder heads are doomed to crack from the very start because of their lightweight construction and design. Aluminum overhead cam (OHC) heads, in particular, are often found to be warped as well as cracked. But so too are many pushrod cast iron heads. One of the causes of cracking in

The Lives of Lifters, What You Need to Know
It’s like any other mechanical part in an engine. It has a simple yet specifically designed function, it’s not overly complicated and it’s definitely not the proverbial rocket science, tricked-out part. But there’s more to know about the valve lifter than you may think. First off, there are two distinct styles of lifters used in
Performance Pistons
Piston manufacturers are introducing new performance pistons for all of these applications as well as refining existing piston designs to reduce weight, and improve strength, durability and ring sealing. Piston design and manufacturing used to be a relatively low-tech process. Now, with the aid of finite element analysis and other computer modeling techniques, many aftermarket
Align Honing Principles
If you ever want to get scared, check out what a crank looks like at high RPM. If you’re interested, the machine to do this with is called a Spintron. What you’ll see is a large, heavy, supposedly rigid chunk of steel squirming around like crazy. You’d swear any metal walking around that much would
Searching For The Complete Clean
Many shops have systems that work well for one but not so well on the other. Are there effective ways to clean both types of metal with one setup? The answer to that depends, in large part, on what you consider clean. Most shops have some type of cleaning equipment, whether it is an automated
Connecting Rod Reconditioning: More to it than you might think
The connecting rod plays a vital role in the engine. But a connecting rod is under tremendous stress, with the weight of the piston sitting on top, changing direction thousands of times per minute. This continuous stopping and changing of direction combined with the weight of the piston and speed of the engine hammer on
Crankshafts:Stock and Performance
The crankshaft is the working arm of the engine. All the force generated by combustion and the downward motion of the pistons is focused on the crank throws. The leverage effect of the force exerted on the crank journals twists the shaft and converts the up-and-down reciprocating motion of the pistons into rotational motion of

Gessford Machine, 2004 Machine Shop of the Year
If you asked a roomful of people to make a list of the 20 most exciting cities in the world, you would probably find New York, London, Paris, Rome and Beijing on every list. While the exact order and final tally of cities might vary, it’s unlikely that Hastings, NE, would even be mentioned. But
Surfacing Equipment Options
On older cast iron engines with conventional soft-faced head gaskets, as long as the surface finish on the cylinder head and block deck is roughly 60 to 100 microinches Ra (roughness average), the head gasket should cold seal and remain leak-free for the life of the engine. But on late model bimetal (aluminum head/cast iron
What’s Hot In Performance – Cams, Lifters & Rockers
The camshaft is really the heart of every performance engine because the cam defines the engine’s breathing potential, its torque curve and peak horsepower. The camshaft controls when the valves open, how quickly they open, how far they open (with some help from the rocker arms), how long the valves are held open, and when
Ford Timing Chains and Belts
So if a customer is driving a vehicle that is more than 5 or 6 years old, he may be driving on borrowed time if the timing belt has not been replaced. The risk of belt failure goes up sharply once a belt surpasses its recommended replacement interval, which for most Ford applications (except the
Sprint Car Motors
While the World of Outlaws, the All Stars, and USAC are the most well known of the sprint car racing organizations in this country, there are nearly fifty organizations that sanction sprint car racing. In addition, that doesn’t take into account the racetracks throughout the country that have their own division of sprint cars. Although
Rebuilding The Chrysler 2.7L
It was rated at 200 HP and it was originally used as the base motor in the Intrepid and Concorde, but it’s been the optional engine in the Stratus and Sebring since 2001 and it will be the standard engine in Chrysler’s new 300 sedan that’s coming out later this year. So, while there are
