Advances in Engine Component Surface Finishes
For their part, parts suppliers are often sympathetic to the concerns of engine builders. Alan Davis from Eagle Specialty explains: “There have been a lot of ‘snake oils’ and ‘voodoo’ in the past. Any results you can’t quantify by obvious results on the dyno or by other tests are risky at best.” Anyone who has
Must Have Tools For Engine Building Glory
While engine builders still need a fair share of box end wrenches and screwdrivers, we have assumed you didn’t make it this far without these necessities. Instead, we will focus on the specialty tools and equipment you need to get the job done and out the door to your customer. We talked to tool suppliers

Unlocking LS Stroker Engine Potential
Editor’s Note: Our March 2013 Issue will feature the 6th Annual Engine Builder Stroker Guide with a detailed listing, broken down by engine, of the components and part numbers currently available. Be sure to stay tuned! Modifying the LS for more power is as easy as falling off a log, to a point, then some
Rebuilding the Chevy 3.4L/3.5L Engine
(Download the illustrated pdf here) We’re going to take a look at two of these engines, including both versions of the latest 3.4L that was used in the Chevy Equinox (and Pontiac Torrent) and the original 3.5L that was installed in several ’04-’07 Chevy cars and crossovers. And, we’ll give you an overview of what
Exhausting Emissions Questions
It’s kind of funny because 20 years ago, no one wanted a clacking bucket of bolts, let alone have to work on one of these diesel engines. That was simply how the diesel engine was viewed. Now, mid-size trucks offer reliable power, awesome torque, quiet engines and decent fuel economy from a vehicle that can
Today’s Cylinder Block Choices Broader Than Ever
In this case, “best” power means that the engine does exactly what the driver – regardless of racing type – wants it to do, when he wants it to do it. It also helps the driver’s winning percentage if the engine makes it to the end of the race. Remember that old saying: “To finish
Evolving Crankshaft Designs and Applications
In the early days, a crank didn’t have to be very sophisticated or strong because most engines were an inline design, and the loads and speeds were relatively low. Fast forward to today. The evolution in engine technology, power and performance has led to a whole new generation of performance crankshafts that are a mechanical
Dyno Decisions Depend on Business Model
If you need a dyno only three or four times a year, you’re probably better off renting dyno time from another facility. If you build race engines for a living, an engine dyno is an essential part of how you do your job and ultimately the value you provide to your customer. So what are
The Business Case For Buying a CNC Machine
Like a good chef, a good machinist does a lot by feel and experience. These things can’t be learned in a few hours or even days – it takes years. When it comes to CNC machines, sometimes the sum equals more than its parts – but many times the parts generate more than its sum.
Balancing And The Bottom Line
Balancing, once considered to be important in this industry only to performance engine builders, has lately become a sought-after service in some segments you may never have considered. Yet good-old-fashioned engine balancing remains an important profit center in many machine shop operations. If the engine components (pistons, rods and crankshaft) aren’t in balance you’ll experience
Your Shop Machines Have No Idea If They
Shop machines don’t have a clue that your tooling is dull, bent, nicked, burred, or the wrong size. It does exactly what you direct it to do, and if your tooling isn’t up to spec you’ll surely junk out a work piece in record time. Let’s start with tooling made from carbide. Carbide tooling comes
