Ensuring Your Insurance

In the business of engine building there are numerous insurance coverages that you may be aware of and already have, but there are several that you may not know even existed that could help your business in case something happens.

Classic Packard Engines

That Packard name. It conjures up thoughts of the rich, the famous, long limos along with the brand’s perfectly molded fenders and hoods. You get the idea! That was the theme that the Packard company strived for, but for period motorheads and engine builders, those skillfully-built engines that fit in all types of racing machines were of more interest.

Engine Bearings – Main and Rod

The bearings that support the crankshaft play a critical role in handling the power the engine produces as well as engine durability. Because of this, bearing selection, fit and installation can make or break your engine build.

Honing Aluminum Blocks

Manufacturers who produce “linerless” hypereutectic aluminum blocks today include Audi, BMW, Honda, Mercedes, Porsche, Volkswagen, Volvo, and Yamaha. Most late-model engines have aluminum blocks to save weight, including most of the familiar domestic V8s such as Chevy LS, Ford 4.6L modular and 5.0L Coyote, and Chrysler 5.7L and 6.1L Hemi. Yet these have iron sleeves.

High Performance Engine Oils

Now we have break-in oils, high-performance oils, hot rod oils, and turbo oils in addition to traditional racing oils, each developed to be very application specific. So how in the world is the average guy supposed to understand all this new complexity?

Valve Timing Events and the Order of Importance

If you’ll recall, in the January issue, we got into the nitty gritty details of what makes a camshaft the “right” camshaft. In this issue, we’ll continue the education. Cam class is back in session!

High-Tech Tightening

When you build your engines, you put measured thought into every component you use. From the intake system to the exhaust manifold, everything has its place and nothing is installed without careful consideration. But what about the fasteners? Some of the most critical components are held together with relatively low-cost fasteners including screws, nuts and bolts and studs.

How to Find and Fix Cracks

Cracks are bad news because they never heal themselves. Once a crack starts, it always gets worse. Checking critical engine parts and castings is time well spent if it heads off a major problem that might result in a major engine issue or a warranty claim.

A Hell of a Good Year

The folks at Dougans Racing Engines won a lot in 2015. A banner year, according to Ray Field, owner of Dougans. It was this success coupled with the shop’s rich history that helped Dougans’ nomination get selected as the 2015 Performance Engine Builder of the Year, sponsored by Speed-Pro POWERFORGED Pistons and Engine Builder magazine.

Going Faster in 1954

I have a large library in my office consisting of Hot Rod How-to books and annuals from the 1940s, ‘50s and ‘60s. During one of my recent review sessions I found a chapter introducing nitromethane and its use for drag racing. Keep in mind this is 1954 technology…

Shop Solutions March 2016

When vacuum checking 4-valve-per-cylinder heads, it’s hard to tell if it’s both or just one valve that’s leaking. Use your vacuum tester and one of those long inexpensive BBQ or candlestick lighters. Hold the lighter close to the valves and the leaking vacuum will pull the flame in, making it easy to tell which one is leaking.

Valves and Seats

The valves and seats in an internal combustion engine play a central role in engine breathing, compression, performance and longevity. It doesn’t matter if an engine has two, three, four or even five valves per cylinder or if the engine is gas or diesel because the valves all do the same thing: they open and close to allow air into the cylinders and exhaust to exit the cylinders.
