When it comes to improving horsepower, one of the main names is Magna Charger. Long known for its supercharger systems for Chevy pickups and even hot rods, Magna Charger has more recently turned its attention to the Blue Oval. It was in late 2005 that the company introduced a system for the ’04-’06 Ford F-150 pickup truck equipped with the 5.4-liter Triton engine. Aiming to improve horsepower and torque in the 1,200-5,500-rpm range, Magna Charger chose to utilize its fifth-generation MP112 hybrid Roots-style supercharger system in this effort. The Gen 5 is equipped with an internal bypass valve, which the Magna Charger folks say reduces parasitic losses while cruising for increased efficiency and economy. Also, the Magna Charger system is intercooled, and everyone knows that cool air is denser than hot air, and denser air makes more power.

Now, it may seem crazy that anyone would take sandpaper to a new paint job, but if you want to have a glass-like finish that is exactly what happens. Of course, it is special sandpaper, and the person doing the work needs to know exactly what he is doing or that paint job can be toast. One of the things that makes color sanding possible is that the paper used is meant to be wet while the job is taking place. The water not only works as a lubricant, but it also removes the fine paint sludge from the area. The problem is getting that water in the proper place and having enough of it to do the job. After all, who really likes sticking his arm into a cold bucket of water time after time?

The Power Programmer is designed so that once the parameters are established and loaded, the unit is pulled and the program remains in the onboard computer until you elect to remove it. The HyperPAC is different; this unit stays in place. In addition to the three stages of performance tuning—the HyperPAC has all of the performance programming benefits of the Power Programmer—it also has diagnostics; an engine monitor with a complete gauge display; a dynamometer, which includes such items such as a horsepower graph; and our favorite, a dragstrip program. This program actually monitors real-time engine operating conditions, has a Christmas tree start, displays a timeslip and will provide you with “magazine-type road test” acceleration times in 10-mile increments. It will record and display important engine operating conditions throughout the run and will display drive wheel horsepower versus vehicle speed after each run—in both table and graph formats.

The owner of this ’77 Chevy pickup got tired of the performance and poor fuel economy of the truck’s 350 small block, and rather than rebuild the engine, he decided to replace it with something better. If there’s an engine better than a small-block Chevy, it’s one of Chevy’s new Gen-III small-block engines, which include the Vortec truck motors, LS1/LS6, and even the new LS2/LS7.

It can be argued that one of the best mods you can make to an LS-based or Gen III motor is a camshaft change. With the number of aftermarket companies making many different types, a good cam can be found for anywhere from $300 to $1,000, depending upon what type of power you want to make and how sophisticated the cam package is. Because 99.99 percent of all vehicles on the road today are computer controlled, most aftermarket companies are able to suggest whether a new tune will be necessary or if the stock one will suffice. But with so many different options out there, it can be quite confusing as to which is the right one for you.

Those who longed for their engines to look as they did back in the old days of multiple-carb setups were out of luck. Cool as they were to look at, there are lots of reasons why the multi-carb setup fell out of favor, and most of them had to do with the fact that they were a bear to sync. The advent of the four-barrel carb was the death for these systems, though the purists among us prayed for a breakthrough. Thanks to Ken Farrell and his company, Retro Tek, those prayers have been answered. Farrell started off converting old mechanical fuel injection systems (Hilborn & Enderle) when the first aftermarket EFI systems became available. His new system, which uses the latest in EFI mated together with the classic Stromburg 97 design, came about when Farrell saw that there was interest in the benefits of EFI, but he also knew that they were lacking in the looks department. The idea was simple take the best aspects of both and add them together.
