Late Model
One of the most misunderstood performance components on any engine has to be the camshaft, or camshafts in the case of our overhead-cam 4.6-liter Ford engine. The difficulty is only compounded when you add forced induction to the mix. From an anatomical standpoint, the camshaft can be likened to the brain, as the cam profile determines how effectively (when and where) breathing takes place.
In the fall of 2003, I wanted to attend an open-track lapping day with my ʼ67 RS/SS Camaro. I have owned the car for several years and have autocrossed and drag raced it, but I never had the opportunity to run it at one of the local tracks, such as Nelson Ledges of mid Ohio, or BeaverRun.
After seeing several ʼ05 Mustangs fitted with StopTech brakes on display at various shows, we made it a point to talk with them about the system they have designed for this car. The result was an impromptu testing session at the California Speedway in Fontana. As it turns out, just because the company had developed a kit that fit the Mustang didnʼt mean they were finished—not by a long shot.
If you are towing your rig with a ’99-’06 General Motors truck, or a Chevy or GMC vehicle, there’s a good chance you have experienced a strange clunking noise when making slow turns. The clunking noise seems to originate from within the steering column, and some owners can actually feel a small vibration in conjunction with the clunking. If you have encountered this problem, it’s not your imagination, as there appears to be a unique conundrum associated with Chevy and GMC pickups, and their corresponding SUVs.
The Specialty Equipment Market Association (SEMA) Show engulfs Fabulous Las Vegas annually. It brings together the biggest names in the automotive world to show off the latest and greatest, whether it’s new products, amazing custom builds, or the newest trends. TheAutoBuilder is excited to be in the thick of it all.
While the factory cast-iron four-barrel Q-Jet intake manifolds have performed admirably on literally thousands of GM applications—and if you are picking your engine from a used lot to use in a swap, it will likely be so equipped—every last one of them should be torn off the car and thrown in the dumpster.
Have you ever noticed how some people can take their car to the strip and look as if they’ve raced all their lives, while others look totally out of control in the bleach box and during staging? More often than not, the driver with the calm, cool and collected approach seems to regularly trigger the win light. The reason for this smoothness isn’t completely initiated by the driver; in most instances, it is the correlation between man and machine.
If you are driving down the highway in an older car, you are at a major disadvantage if you have to make a quick stop. Many of the high-performance cars being built today have fantastic stopping power, and if you can’t stop as well as the car in front of you, that could certainly be a big problem. The owner of this ’55 Chevy improved it with front disc brakes that work well, but he wanted the Chevy to stop even better, so he decided to add rear disc brakes.
Replacing interior components is not usually that difficult, but interior repair–especially seat repair–requires skills, equipment and training which many enthusiasts may not have acquired. To find out what it takes to make a replacement seat, we went to the Performance Choice division of Mid America Motorworks in Effingham, Illinois.
In the eyes of the Chevy enthusiast, ultimate acceleration reigns supreme. Everything plays second fiddle in the performance-oriented minds of many enthusiasts, including handling, comfort and so on—besides, those things are tough to quantify. Acceleration and top speed are what we are into and unfortunately, all too often, last on the performance priority list is braking. Remember, no matter how quick or fast a particular Chevy is, and no matter how well that Bow Tie handles, no matter how plush it is, no matter how straight the body panels are or how crafty it’s built, eventually you have to get the thing to stop.Â
