Street Performance Valvetrains
Street performance requires everyday driveability and reliability. A good street performance engine should have a broad torque curve, plenty of low end power and a reasonable amount of intake vacuum at idle, especially if the engine is backed with an automatic transmission. A street engine also has to be capable of lasting tens of thousands
The More Things Change…
One of the things we editorial-types like best is hearing from you, our readers. Obviously, we can’t talk with each one of you in person during the week, so it’s always a treat when someone comes up to me at a trade show or business convention and lets me know they appreciate receiving Engine Builder
Race & Performance Expo Wrap-Up
The Race & Performance Expo kicked off Friday, March 5 with the manufacturer’s Mardi Gras party that included a round table talk with Vic Edelbrock, Tim Freeman and Jim Bingham about the Hot Rodders of Tomorrow Engine Challenge program. The evening concluded with a tribute and award presentation to Theresa and Amanda Gabriel, the wife
Jack Roush Honored with Robert E. Petersen Lifetime Achievement Award
OnMarch 12 Jack Roush was given one of the highest honors inthe hot rod world, when he was presented with the Robert E. PetersenLifetime Achievement Award. The ceremony took place during the grandopening breakfast of the 12th Annual HotRod & RestorationTradeShow, in front of nearly 1,000 attendees at the Indiana ConventionCenter in Indianapolis. “Being
Stroker Motor Opportunities: Love the One You’re With
Let’s face it: there are only so many 340 Chryslers, Boss 302s, 427 medium risers and 440 Six-pack engines out there. Luckily, many combinations of less-familiar engine components are readily available and can rescue you from the cookie cutter mentality. A quick inspection of a few of the many forged piston manufacturers’ catalogs reveals a
CNC?Head Porting & Machining Centers
The fact that CNC machines have come down in price over the years, coupled with less complicated interfacing systems means that today they can be used by nearly anyone. You don’t have to relearn everything. You don’t have to take endless courses on how to make a tool change. Today’s machines are sophisticated and savvy
AERA to hold Don Gross Regional Conference
AERA is doing its part to make gaining knowledge and networking opportunities easier by holding a series of regional conferences instead of a larger, national one. Along with the outlined technical programs, AERA is inviting leading manufacturers of engine building/rebuilding tools, supplies, services, parts and machinery to attend this conference. These suppliers will have table-top
Spring, Sprang, Sprung: Why Valve Springs Matter So Much
Keep in mind the cam, pushrods, lifters, and rocker arms do all the work in opening the valves, but it is the spring that keeps that valve closed during the operation of the engine. Valve springs can be compressed and expanded throughout their life cycle, sometimes at more than 1,150 times per minute for most
Selling Vintage Speed Can Help Business Until Business Gets Better
Due to these hard times, fewer customers are looking for your services, and they’re looking to spend as little money as possible. A small shop can survive on low-margin jobs for only so long before the overhead simply eats you alive. One alternative plan is to add a line of vintage performance engines that command
Caburetors and Electronic Fuel Injection Systems
These days just about everyone is looking to new technology to solve their problems. In some cases it makes sense: others, not so much. Take the trusty old carburetor for example: it has been around since the beginning of time (automotive time anyway), and many have predicted its demise, but somehow it keeps coming back
Street Performance Cylinder Heads
Where I grew up in Connecticut wasn’t the hotbed of street racing like Woodward was in Detroit, but we had the Berlin Turnpike, River Road in Middletown, plus a few local small-town hotspots. It was during this period that I got my first education about the importance of cylinder heads. A local rich kid got
Performance Valve Springs and Retainers
Old school thinking on these matters has usually been to increase spring pressure as much as possible by using the stiffest dual or triple springs that can be installed in the engine. But that kind of thinking is changing, thanks to improvements in spring technology. Stiffer springs are obviously needed if you are building a
Scoping Out the Sport Compact Market
At first it was known as the Import Tuner Market which later morphed into what is currently known as Sport Compact. However, the market could be changing again and may soon be called something else. Last year, the Specialty Equipment Market Association (SEMA) changed the name of its Sport Compact Council to Street Performance Council
Crankshafts and Bearings for Street Performance and Racing
Most engine builders have strong opinions and brand preferences when it comes to choosing a crankshaft and bearing combination for a performance engine application. Their preferences (and prejudices) are usually based on years of experience, both good and bad. Many subscribe to the philosophy that “if it isn’t broke, don’t fix it!” Consequently, if they
Balance of Power
Everyone is looking for balance in their lives – balance between work and family, between responsibility and recreation, between give and take. Too much of one at the expense of the other can lead to dire consequences. The same thing can be said about the engines you rebuild. Balance between the crankshaft and its related
Cleaning: Different Methods for Different Needs
Back in the late 1800s, the director of the U.S. Patent Office was said to remark “Everything that can be invented has been invented.” Charles Duell, U.S. Patent Commissioner in 1899 reportedly told the President of the United States that there was no more innovation and, therefore, no more need for the patent office. Except
Boosting Performance – Nitrous, Superchargers and Turbochargers
From the budget six-cylinders that get 300 hp and 28 mpg for less than $25,000 to the 600 hp Viper V10 to the 630 hp Corvette ZR1 for just over $100,000, the performance market is deep and wide. “It’s amazing, the horsepower potential that these cars are coming with off the factory floor,” says Frank
Performance Rocker Arm & Shaft Systems – Time-Tested Technology Provides Proven Performance
The SB Chevy ball and stud stamped steel rocker arms were a revolutionary departure from the shaft mounted rocker arm systems of that era because they allowed it to outrev its competitors. More revs means more airflow and more power. It wasn’t until 1962 that Ford finally dumped their old Y-block 312 rocker shaft engine
