Performance Gaskets & Surface Finishes

The most critical engine gaskets are the head gaskets since they have to withstand the heat and pressure of combustion. And unless the engine is a drag motor with a solid billet or filled block, the head gaskets also have to keep coolant out of the cylinders.   Many performance engines are capable of making

Valve Seats & Guides

Most engine builders worth their salt know that with the components and technology available today, it’s not that difficult of a task to make horsepower. With the availability of so many performance parts – whether it’s from the OEM or the aftermarket – engine builders can pull from vast resources to achieve a balance between

Not Quite a Full Pull

In tractor pulling parlance, a “hook” is when you  attempt a pull. A “full pull” is one in which you go the maximum distance of 300 feet. At Engine Builder, we’re mourning one of our own, who made the hook, but didn’t quite get the full pull. Jim Walbolt, who had been a contributor to

Tuning In To The EFI Market

There are many variables that need to be calculated and calibrated when it comes to electronic fuel injection (EFI), but simple fuel flow is just the beginning. EFI goes far beyond a replacement for a carburetor, and the electronic part of the equation is where these systems seem so complicated. Many EFI systems give you

HPBG: Choosing Aftermarket Cylinder Heads

If the performance business is about one thing – it’s about improving upon what comes in the door and making it better for your customer’s application, whether he’s racing down the quarter mile, hitting the twists and turns of a natural road course, or just driving it to the movie theater with his girl by


One of the only ways you can prove your worth as a race engine builder – besides on the racetrack, of course – is on a dynamometer. Being a shop without a dyno may be akin to running blindfolded: you can surely build a good engine, even a winning engine, but you probably won’t know

Camshaft & Valvetrain Technology Overview

Camshaft and valvetrain technology is a topic we’ve written much about over the years. A rotating eccentric lobe on a camshaft still opens the valves. In the case of an overhead valve engine, the cam lobe pushes a follower or bucket tappet to open the valve. With a pushrod engine, the cam lobe pushes a

Power Adders: Turbos, Blowers and Nitrous

The engine can only inhale so much air because the atmospheric force that’s pushing air into the engine is only 14.7 lbs. per square inch at sea level. To make matters worse, atmospheric pressure decreases with elevation. Air density also decreases with temperature because hot air is thinner than cold air. Most stock naturally aspirated engines

Making Dollars and Sense Cleaning Blocks, Heads

Unless you’re starting with all new parts, cleaning is as important to your engine build as disassembly, inspection, machining and reassembly. Without taking the cylinder heads and engine blocks down to bare metal, you can’t properly inspect the castings for cracks, wear and other defects. For something so important, proper cleaning technique is often misunderstood, overlooked

Designing and Building a World-Record Beating Porsche V8

We would build for the Blown Gas Modified Sports (BGMS) class where the record is currently 231.5 mph. Another record we were after was the Porsche marquee record for the 928 of 205.6 mph. Our math told us that – because we knew our final drive ratio, tire diameters and engine redline; and if our
