Step by Step: 6.4L Magnum Coming to Life
I recently had my forth call from a shop with interest in our 392 ci Chrysler build as a project they are hoping to tackle. The budget and power needs for his project were not to the scope of our project and he was discussing a less expensive cast steel crankshaft and the factory connecting

In Depth Deck Discussion I’ve found another use for a deck height bridge. When replacing seats on race cylinder heads, especially Big Block Chevys, I use a deck bridge with an indicator extension to first check where the valve was and should be. Then, when machining the seats, it’s an easy way to get all
Green Strategies: Propane – A Gas on the Rise
The issue of the automotive and heavy-duty industry moving toward more alternative fuel useage will always be an important topic of discussion for the rebuilding industry. And, no matter which side of the fence you are on regarding a reduction in petroleum in today’s vehicles, alternative fuels may provide more engine-related opportunities to your business.

Serve Up Cylinder Support on a Torque Plate Honing motorcycle or powersport cylinders can be difficult. The thin bottom portion of the cylinder often protrudes 1”-3” below the cylinder assembly, and if this thin/bottom portion of the cylinder is not supported during the honing process, the hone tends to push the cylinders outward instead of
Learning To Race Pro Stock
My transition in 1975 from bracket racing a 122˝ wheelbase mid-eleven second, two-ton ’57 Mercury to racing in a low nine-second 99˝ wheelbase, Pinto Pro Stock car, was quite a jump. I was jaded with bracket racing and wanted to run heads up – all out with a door car. So, Pro Stock was it.

Choosing Camshafts – Picking Performance
Choosing the “right” camshaft is not only the cornerstone of building a performance engine, but also its centerpiece. Choosing a cam can give anyone a headache – especially if they choose the wrong cam for a given application. There’s a lot of science involved in cam selection, so keep reading and we’ll help you
New 2014 Dura-Bond Catalog Available
The new catalog features many new applications complete with photos, competitors’ interchange, conversion reference charts, and a powder metal valve seat technical information and installation instruction manual. Company: Dura-Bond Bearing Company www.dura-bondbearing.com Dura-Bond Bearing Company recently introduced its new 2014 engine parts catalog that includes the following feature items: • The “All-Round Cam Bearings” • Oversize
Cylinder Head Porting
Huge flow numbers may be impressive, but optimizing airflow at mid-valve lift is key to power. If airflow though a valve port is plotted on a graph for the entire valve cycle (from opening to peak lift and back to close), the area under the curve is total airflow, which corresponds to total power. So
Cleaning Engine Blocks & Engine Cylinder Heads
Cleaning engine blocks and cylinder heads is just as important as the machining operations you will perform on the castings. You can’t do a thorough job of inspecting these parts if they are dirty, greasy or covered with paint or corrosion. Checking for cracks in cast iron heads and blocks requires a clean surface for
Parts Making With Your CNC
Computer Numeric Controlled (CNC) machining allows engine builders to achieve almost unbelievable levels of accuracy and consistency. The programmability of a digital computer not only automates the operation of the equipment but also provides a level of repeatability that can’t be matched by manual equipment. That’s why CNC has been the backbone of virtually all
Pursuing The Small Engine Market
Small engines are everywhere. They power lawn mowers, garden tillers, portable generators, all kinds of pumps, go-carts, ATVs, snowmobiles, motorcycles, forklifts, even refrigerated trailers on reefer trucks. Most of these engines are single-cylinder four-stroke air-cooled motors that range in power from 5 to 15 hp or more. Some have vertical crankshafts and some have horizontal
‘Heads Up’ On Today’s Cylinder Heads & Bolts
Some say the air cleaner of an engine is like the front door of a house. That is, it’s what you see first and foremost. And the home owner can use that door to make a statement about the house without anyone seeing what’s inside. Much like what an air cleaner says about an engine
Going Green Not Just for Irish
Did you know that as engine builders, we were green long before green became the IN thing? We were green even before Kermit said it wasn’t easy. How are we green, you ask? We are green because we rebuild, which means we recycle. Green is defined as: • Relating to or being an environmentalist

Safe Valve Spring Break-In Most engine builders are well aware of the fact that high performance valve springs should be compressed to coil bind through several cycles before being installed. The problem with this procedure is that it can be time consuming, costly and even dangerous. It is time consuming if each spring is compressed
World’s Smallest V8 Engine
Gary Conley’s 30-year quest to manufacture a true production V8 engine in quarter-scale almost went up in smoke twice, once in 2001 when a foundry fire claimed all his critical molds, and later when oil smoke proved a stubborn problem during run-offs of the engine. Conley overcame the first setback with years of sheer determination.
Warranties Are Everyone’s Problem
Warranty! The word shouted from the other end of the telephone can cause some people to wake up screaming in the night. It seems that warranty problems grow exponentially – once one comes in they seem to multiply just in time to ruin a good month’s sales results. Who’s Fault Is It? Usually it’s yours
HPBG: Burnt Aluminum and Motor Oil
It’s a late-August Sunday in 1988 and I am staging up my Outlaw Pro Stocker for the final at the World Series of Drag Racing at Cordova, IL. I am driving my legendary ’79 Mercury Zephyr (Zeke) powered by the NOS assisted 1,600 hp “Monolith,” a 672-inch Kaase Boss Hemi Ford engine. I need
Cashing In On The Cafe Racer, Vintage Bike Revival
The Rockers who rode on the racy-looking machines sculpted after grand prix motorcycles gained the nickname “cafe racers” because they were often seen parked outside a coffee shop and were considered wannabe racers. The name was originally intended to be an insult but later turned out to be a proud moniker. A right of passage
Trend Performance Seeking New Facility in North Carolina
Originally a plan was devised to open an office in the Asheville area, but when Chuck Jones, former general manager of the PPP Center, recently joined the company, more ambitious plans took hold. “I’ve always admired Chuck’s work ethic,” says Trend’s engineering director, Andy Anderson. “He works hard, he bites the bullet, and he still
