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

Taming The New Tiger

Say the name Arnie “Farmer” Beswick and many an old Pontiac fan will nod and share a story or two about Arnie and his legendary GTO, the Tameless Tiger. About two hours down the highway in Illinois, Jim Riskovsky, owner of Turbo Connection in Edwardsville, IL, is learning to tame his own tiger, his 2005

With K-Line’s long history and expertise in tool and die manufacturingand SBI’s quarter-century of experience and innovation in marketing anddistribution of its

Balance of Power (and Profit)

One of the keys to a smooth running, long lasting engine is proper balance of the reciprocating and rotating parts. When a crankshaft is out of balance, the uneven distribution of weight can generate centripetal forces that shake the engine with increasing intensity as engine rpm goes up. Centripetal force (which many people mistakenly call

Choosing A Replacement Camshaft

Unless you are doing a totally stock rebuild and reusing the original camshaft, selecting a camshaft depends on what kind of engine you are building and how that engine will be used. A stock engine for a daily driver is obviously an entirely different application than an big stroker motor for a Pro Stock racer. 

From ATVs to Karting to Everything In Between

While small engines are in many types of equipment and toys, there isn’t anything small about their potential for engine builders to make a profit. From karts to all-terrain vehicles (ATVs) to motorcycles, for many engine builders looking to add profit margins to their business or to get into a specialized area of the industry,

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

Solution for Pre-mature Camshaft Failure on Big Block Chevy Engines ≈Big Block Chevrolet engines are well known for being subject to premature camshaft lobe wear and failure. Here are ways to help relieve this problem. When replacing a hydraulic camshaft, instead of using the OE type of lifter (p/n 817 or VL37) use p/n 2095

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

Coretalk: Key Industry Speakers Slated For PERA’s Chicago Convention

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

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

Rocker Arm- Form & Function

For all the changes in the performance engine over the years, one constant remains – no matter what series they’re running, no matter what the payout, no matter if it’s just a couple of guys trying to outdo each other stoplight to stoplight, racers will often spend money they don’t have in search of the

Stroker Engine Kits

For more than 50 years the old saying “There’s no substitute for cubic inches” has been the credo of nearly every racer and hot rodder. Whoever created this unwritten universal law could never have imagined to what extremes today’s speed enthusiasts would take it. Now, unless you have a 420cid-plus small-block or a 550cid-plus big-block

Dynamometers and Dyno Operating Systems

The data collected while an engine is running on a dyno can be analyzed to maximize the power gains from various modifications (changes in the fuel mixture, ignition timing, valve timing, compression, the induction system, exhaust system, etc.). Performance engine builders use dynos to measure horsepower and torque so they can optimize engine performance. By

Tech Notes

Engine Builders: What is viscosity breakdown? All of us in this business understand an SAE 5W-20 oil is thinner in viscosity than an SAE 10W-30 and that the “W” stands for winter, but that’s probably about where it stops even though there is more to the story. Motor oils thin in viscosity as they warm

Diesel Drag Racing, Compression Ignition Engines Smoke The Strip

It is one of the purest forms of American motorsports. One guy pulls up next to another guy at the starting line and revs the engine. A simple glance over, a nod and a green light. In a fury of sound and smoke, the two racers take off down the straight stretch of pavement. If

Q: Are the cracked exhaust seats in the Cummins 5.9L diesel engine found in the Ram pickup a cause for concern? A: The AERA Technical Committee says cracked exhaust seats on 1998-2006 Cummins/Chrysler 5.9L diesel engines have been reported by other AERA members as well. The 24 valve engines with four valves per cylinder have
