Avoiding Workplace Accidents

You’re probably not going to cry over a little spilled paint, but will you or someone else in the shop literally take the fall for a co-worker’s carelessness? The list of situations that can cause injuries is long: spilled paint, oil and grease; polished floors; loose matting and uneven walking surfaces; cluttered walkways and large

Cylinder Head Design & Selection

Choosing the “right” cylinder heads for an engine build can make all the difference in an engine that delivers and one that falls short of its potential. Horsepower, torque and throttle response all depend on how well the cylinder heads, camshaft and induction system work together. Choose the right combination and you’ll build a winner.

Racing Spark Plugs

Choosing a set of racing spark plugs for a particular application is not as easy as it sounds because the plugs have to be closely matched to the application. Stock plugs are fine for stock applications and ordinary driving conditions. But when an engine is modified to make more power and is run under racing

Crank Grinding – The Myth of the .010”/.010” Crankshaft

Regrinding the crankshaft is an important part of the engine rebuilding process. It was almost an art in the ‘40s, but it’s pretty routine now. However, there are still plenty of myths and misunderstandings that are left over from the past that we still have to deal with today. One of the most common myths

REBUILDING THE 5.7L HEMI

Back in the early ’90s, when Chrysler realized that it would need a new truck motor to replace its 318/360 Magnum engines to meet the coming emissions standards, the company considered two pushrod engines along with one SOHC design and concluded that a pushrod motor with a pair of Hemi heads that really breathed would

Reusing, Reclaiming, Remanufacturing – Whatever you call it, it’s how the industry recycles parts and components

No matter what kind of engine builder or remanufacturer you may be or what applications you build for, at some point in time you’re going to run into a situation where a used engine part or component will come in handy. You’ll reuse, reclaim or remanufacture it for your specific job. Whatever the reason may

Wet & Dry Sump Oiling Systems – Choosing the Right System for the Right Job

If you are building a customer’s “dream engine” what type of oiling system should you use? The answer to that question will depend on the application (street, drag, circle track, road race, off-road or marine), engine RPM and how much your customer is willing to invest in a lubrication system. Your choices may also be

Midget Engines – Perfect Power from Pint-Size Performers

Midget open-wheel racecars and the Stock (S Class) and Modified (A Class) inboard hydroplanes have provided thrills and chills for racing fans since the 1930s. And as the speed and performance of these radically-different racing machines has improved, so have the engines that power them. These engines have varied from stock four and six-cylinder automotive-type

Learning Curve – Understanding the Evolution of Cylinder Head Seat and Guide Machines

Like many of you, I’ve been watching the transition in head machines for the engine machinist industry with great interest. And you and I both are looking at how changes in equipment will impact your business. You see, I teach in an engine machinist program and when I took over the program in 1993 our

UNDERSTANDING ROD RATIOS

Performance engine builders are always looking at changes they can make that will give their engine an edge over the competition. Rod ratio is one of those factors that may make a difference. Changing the length of the rods with respect to the stroke of the crankshaft offers some advantages in certain situations, and may

Brighton, MI High School Engine Building Program Includes Dyno Instruction

Stop me if you’ve heard this story before: a couple of guys get ahold of a tired late model Chevy 350 V8 and decide to rebuild it into something with a bit more teeth. With the help of a more experienced engine builder they spend about a year working on the block and heads and

NTPA Tractor Pulling Powerplants – Big Size, Big Horses, Big Torque

Tractor pulling in America means a lot of things to different people. Many in the general public regard the sport as nothing more than stock trucks and tractors coming in off the farm and doing their thing at the county fair. That was then, this is now. The sport has grown from those humble roots
