Engine
If you’ve ever imagined a time when you could simply pick up the phone or send an e-mail to General Motors and order the engine of your dreams, pull it out of a box delivered to your door and plug it into the car of your dreams, then stop dreaming as that time has come. While it’s not new information that GM Performance Parts provides an assortment of engines to choose from, it’s never been easier to select the one that is best for your budget and the intended purpose of your car.
When GM introduced the Gen III small block in the F-body, it rekindled a dying performance flame with its new-generation small block. While the Gen I small block actually kick-started the hobby and got it into gear, it’s the latest family of small-block engines that has grabbed the attention of enthusiasts everywhere—and for good reason.
Cam-speak is a language all its own. Well, maybe not from a linguistic point of view, but it is a specialized dialect of car-guy talk. Although spoken by a good portion of enthusiasts, Cam-speak is really fully understood by only a handful of those same enthusiasts, as it is a very specialized, nuanced dialect. Those who do not speak the lingo can instantly be singled out. Those who are fluent in cam-speak are listened to intently, even when those listening do not fully comprehend whatʼs being said and how to apply it to their particular applications. Few within our ranks are particularly fluent in this highly specialized jargon.
There are few modifications that can be made to an engine that can give both increased performance and better fuel economy. In these days of increased gasoline prices (nearly $4.50 per gallon), fuel mileage is an important consideration for vintage trucks that owners consider their daily drivers. For many reasons, vintage pickups are becoming not just weekend toys but also weekday workers. And one of the best ways to increase both performance and mileage is with an electronic fuel-injection system.
Would you believe that one of these cams could provide an extra 200 hp to your combination? It’s true. Actually, the truth is that the installation of a stock cam will cost you as much as 200 hp.
If you have a 1992-2000 Chevrolet or GMC with a 6.5L and you’re worried about overheating issues, there’s no reason to sweat it. Our friends at Dieselsite have the solution.
Ford fans will always have a soft spot in their blue-oval hearts for the Windsor, the Cleveland and the big 460 FE engines—and deservedly so. If you’ve ever crawled a junkyard for one of these engines, you’ve likely passed over more than a few 351M and 400 engines to find what you are looking for. Poor factory numbers and bad word-of-mouth have made these cousins to the mighty Cleveland about as wanted as poison ivy at a nudist colony, but there is power to be found in those engines—and cheap, too.
We showed you how to build a small-block engine that could make over 500 hp and 500 lb-ft of torque on 87-octane gas. It was a motor that could be driven just about every day with a hydraulic-roller cam and a good carburetor, making acquisition and maintenance almost nonexistent. Like many things we do in the engine world, the results we enjoyed—while good—just weren’t satisfying anymore. We wanted more.
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.
