Automatic transmissions have been around nearly as long as the automobile. They served their purpose, but for those who were looking for performance, the manual gearbox was the way to go. And the more gears in that box the better. Even though high gear is traditionally a 1:1 setup, having many gears to choose from makes keeping the engine in the meat of the power band that much easier. The “three on the tree” became a four, then five, and finally six speeds capable of handling whatever the driver/racer asked of it. Of course, this was all via a floor-mounted shifter usually using an “H” pattern. (more…)

As any racer will tell you, you can’t drive any faster than you have the ability to stop. Brakes allow you to have the confidence to drive deep into the corner, apply the brakes and drive on through. Our heavy Mustang (around 4,000 pounds in convertible trim) was running strong with plenty of power from the Magnacharger induction system, but required some help in the braking department. To the rescue came Baer Brakes. (more…)
It’s been said that it’s better to look good than to feel good, but what if you want to have both? That analogy especially works with your engine. Everyone wants to have a mill that looks good, but it has to work well, too. And as if that weren’t enough, nobody wants to spend all weekend bolting on new parts when they could be out cruisin’. That’s why for our first installment of “Weekend Update,” we are featuring the installation of a B&B Street Rods serpentine belt system and an aluminum radiator from U.S. Radiator. (more…)
Every project, whether automotive or home improvement, is only as good as the foundation on which it is built. Some perfect examples are the 40-plus-year-old projects that grace the pages of this magazine every issue. Most of the muscle cars that we love to read about were at one time worn out shells of their former Detroit glory, in dire need of restoration. (more…)
Strap yourself in for another installment of Project Flat-Footed. This ’67 Camaro being built at Ironworks Speed & Kustom is destined for high speed autocross and road course action, and our mission is to take you through the build all the way from metal repair and bodywork to chassis and suspension updates, plumbing and wiring all the way to the starting line. In the August issue we walked you through chassis and suspension upgrades from Chris Alston Chassisworks, braking upgrades from Wilwood Engineering, and the installation of the wicked LS7 from GM Performance Parts.

Pavement rushes under you as you bury the pedal and feel the horsepower glue your back to the seat. You push and pull the gears as you fly through the corners and the meticulously appointed chassis and suspension make child’s play of the twisties. Upgraded big brakes keep the horsepower in check, but the power under your right foot is calling to be released from the stables and you force the throttle southbound and feel the rush as the tach needle climbs and your heart starts to pound.
Horsepower and speed have been at the top of the performance food chain since enthusiasts were dropping warmed over V-8s in hot rods in the ‘40s. Today we are spoiled with fuel-injected and aluminum head-equipped engines that when topped with a blower fuel quick horsepower into the hands of the lucky pilot. Just as tire-igniting horsepower is paramount to the driving experience, being able to control and safely halt that horsepower when the performance blaze gets a bit too hot is also important. Stopping safely when you are pushing your muscle car through the cones or on the road course is important to enjoying the experience behind the wheel with confidence. (more…)
Look under the hood of any vehicle built after around 1990 and you’ll notice one thing in common: They all have an intake system that pulls air from a fender well or from the front of the core support, supplying the engine with fresh cool air for maximum power and efficiency. Why? Because cool air is denser then warm air, which means there is more oxygen packed into every square inch. The higher the oxygen content, the more powerful and efficient your engine will be with every stroke of a piston. Cooler intake air becomes a denser charge, which equals more tire-churning power.

Building a stout power plant for your muscle car is usually the first step in the build. Calculating horsepower and torque helps navigate chassis and suspension set-up as well as transmission and differential needs.
When building a small-block mouse or big-block rat for your pride and joy there are a few roads you can travel. You can pick up a donor block and head for the machine shop, or you can purchase a brand new engine block from Dart Machinery and skip the worries of paper-thin cylinder walls from numerous bore jobs and potential cracks revealed after the hot tank and magna flux sessions. Consider the cost involved with using an original equipment used block. (more…)
