Fuel System
Here’s the deal: if you’re driving a performance car, the last thing you want is factory lag holding you back. You bought it for the thrill, the punch, that raw acceleration that gives you instant gratification. But if you’re tired of stock throttle response getting in the way, The Auto Builder has the answer. We recommend Soler Performance’s DLX Bluetooth Throttle Controller. Your first drive will be mind blowing — it transforms your car into a responsive rocket.
While at LS Fest, we noticed several drivers spending a lot of time tuning their rides before hitting the track, dialing them in to try and gain an edge over the competition. This left us puzzled. If you’re looking for an edge, there’s no better way to optimize your performance with E85 than with a flex fuel system from Advanced Fuel Dynamics.

Holley carburetors have long been a staple in the go-fast world of high-performance motoring, whether it’s NASCAR, drag racing or on the street. Much like other performance-oriented products—perhaps even more so with a carburetor—a carburetor requires a fundamental setup and a degree of maintenance, and that’s considering you have chosen the correct-size carburetor for your application, at least to get it in the ballpark. Knowing how to adjust, maintain and even repair your Holley carburetor goes a long way toward helping to ensure that your carburetor will make optimum horsepower for a long time. Because of this, we decided to compile a few troubleshooting and repair tips for the popular 4150-series Holley carburetor, which is the series designation for Holley’s street/strip and racing carburetors.
Alternative-fuel sources and hybrid cars are all the rage today. Everyone from major automakers to backyard inventors is pursuing alternative fuels and energy sources. While the ultimate goal is generally to eliminate dependence on foreign oil, for hot rodders there is also the desire to invent and create a better-performing engine.
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.

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.
What makes more power: carburetors or computers? While the ultimate answer is that a sophisticated electronic fuel-injection system will virtually always outpower a carburetor, the real question may be whether the power gains are worth the extra expense and complexity of installing an EFI system.
