Valve Seat Technology For Stock and Performance Applications
Valve seats are a critical engine component because they are the foundation of the valvetrain. The seats provide a surface for the valves to seal against when they close so there’s no loss of compression or pressure from the combustion chamber. The seats also help cool the valves by conducting heat away from valves into
Understanding Oval Track Cranks & Rods: There’s more to it than you think
Racing’s racing, right? The first one is the winner and second place is just the first loser. While that may be true as far as it goes, getting across the finish line first takes different techniques depending on the type of racing it is. Racing engines are not immune to specialization.

Vehicle manufacturers like cast iron because it’s cheap compared to most other metals, it is strong and durable, and it can be easily cast and machined to make engine blocks, cylinder heads, crankshafts, connecting rods and other
Horsepower – Building In and Bolting On
I consider myself blessed that for the last 35 years I’ve had the opportunity to hang around with some of the nation’s best engine builders and racers, and had the rare opportunity to pick their brains about engine building tips and tricks. Most of these concepts are pretty well known in the engine building community
Push Rods & Lifters
The pushrods and lifters work with the camshaft and rocker arms to open the engine’s valves. This basic setup has changed little since the earliest days of pushrod engines. The only major change in these components has been roller lifters replacing flat bottom lifters on late model engines. Even so, there’s still a market for

Drag Racing Cylinder Head Selection
Experts say that the key ingredient is high velocity matched with good flow. But the high flow numbers may blind your customers from seeing the whole picture, so it is up to you to explain. Some cylinder head experts compare flow numbers to horsepower numbers on a dyno – but guess what? They’re not all
Marine Motors: Challenges & Opportunities
On the popular British automotive television program “Top Gear,” the hosts were interested in discovering how hard it could possibly be to build a vehicle that was capable of both being driven on the road and sailed in water.

Tech Notes
Engine Builders: One of the great debates in automotive service is oil drain intervals. The correct oil change interval is the one prescribed by the engine manufacturer that can be found in a vehicle owner’s manual. Oil drain interval is determined by the engine type, drive train, vehicle type and expected use. Each OEM tests
High Performance Diesels: ‘Black Smoke’ Tractor Pulling Market
If you’re a lover of horsepower, dirt and "black smoke," you may also have a passion for building engines in the thriving diesel tractor pulling market. These engines aren’t just for working in the fields anymore – they’re full blown, smoke billowing, brute force racing machines – and building them can lead to a bountiful
The Shermanator 347: A 530HP Gas Stroker You Can Build
A while ago Engine Builder ran a story on the popularity and basic dos and don’ts of stroker engines ( March 2007 Engine Builder). It received such great response that we are following up with a “real world” stroker engine buildup. In this case, it is an engine combination that is so popular that it
Scratching The Niche
If you have been a reader of this magazine for any length of time, you’ll know that one thing is certain: this isn’t the same industry it was even just a few years ago. Not so long ago, a car or truck that was more than six years old would have been considered a junker,
Old Iron, Times (and Technology) Change!
For the past 15 years or so I’ve abused the automotive media and the English language with series after series of vintage engine build-ups. These are opus-length ordeals that consume somewhere between 150 and 250 pages and a lot of photos aimed at doing what I can to re-discover and re-invent various vintage engines for
The Ups And Downs Of Valves
It’s always good to take a fresh look at some of the many engine components we work with. Rather than being lulled into complacency, the idea is to see what’s new, what trends are in play and to get a current reading from others on the inside. In other words, it’s good to keep it
Riding the Powersport Wave
If you just look at the number of engines being built year after year – a steady downward trend – it may seem like there is no way to survive in this industry by building production automotive engines. However, most shops that are thriving have found something that gives them an edge. You have to
Resurfacing Cylinder Heads & Blocks? Mistakes to Avoid
Cylinder heads and blocks may need to be resurfaced to restore flatness or to improve the surface finish, or milled to change the deck height for a variety of reasons. The deck surface on the head or block may need to be resurfaced if the surface isn’t smooth or flat. A head may need to
