How to Set-Up and Tune Holley’s Dominator EFI System

Here’s a look at a camshaft in the process of being degreed. As you can see, the cam is driven by a Jesel belt drive, which simplifies the process dramatically (but that's another story). The 14-inch degree wheel is from B&B while the pointer is homemade. (Image/Wayne Scraba)

Pro Tips for Setting Tire Pressure and Adjusting to Changing Track Temperatures

There are many questions related to adjusting tire pressure on a drag car, and it seems everyone has a different opinion. The reality is, every car will require a slightly […]

This dial indicator has been set up to read component runout and zeroed. That means the plunger has been run down part way through the range of travel. Once that is accomplished, the outer dial bezel is rotated to position a zero mark directly on the large needle. You can see here that the photo was taken slightly to one side. It shows the effects of not reading a gauge straight on. (Image/Wayne Scraba)

Shifty Business: How to Install A Shift-Light Tach

Today, big high quality electronic tachometers are a common sight at drag strips and in fast street cars. Modern electronics have turned tachometers into precise and reliable instruments (provided, of […]

This is what the terminals and seals look like up close. Protection from the elements is provided by these special silicone seals.  The terminal pins are the pieces that actually transfer the electrical current. The pins consist of a male and female terminal. These terminals are non-orienting. What that means is they don't have to be turned when they're plugged together (some other waterproof connectors mandate a twist every time you plug them together). The terminal pins have double lock tangs that secure the pin inside the connector. They also incorporate an extra-long spring member that's designed so that the terminal can't loosen once you've installed it.(Image/Wayne Scraba)

How to Make Professional, Weathertight Electrical Connections

Electrical connections that come loose, break, and short-out can become a major headache—especially on a car that relies heavily upon electricity to function.  If the electrical connections aren’t right, they […]

Next, we measured from the axle-housing flange back toward the plumb line. The passenger side measured 25.875-inches while the driver side checked out at 26.875-inches. What’s going on here? Even though the axle tubes welded to the center section are exactly the same width, there’s an inch difference in actual axles. That is the pinion offset. To double-check the numbers, add the pair of measurements together (25.875-inches + 26.875-inches = 52.750-inches). They should be the same as the axle flange-to-axle flange number.

Here’s a close look at an air shifter. While operating, when charged with gas by the solenoid, the cylinder moves the shift lever. There are many air shift kits designed to convert a conventional shifter to CO2 use. This particular example is designed as a dedicated CO2 shifter.  (Image/Wayne Scraba)

This 572 big block Chevy is bolted to the writer’s old (really old!) Lakewood tricycle stand. We’ve used it for more than 40 years (yikes). Yes, it’s a tough old piece, but tricycle stands tend to be wobbly as you move them around the shop. (Image/Wayne Scraba)
