Mopar Performance Engines
A Chrysler Hemi engine, known by the trademark Hemi, is a series of V8 internal combustion engines built by Chrysler that utilize a hemispherical combustion chamber. Chrysler built three generations of hemi engines for automobiles: the first (known as the Chrysler FirePower engine) from 1951 - 1958, the second from 1964 - 1971, and the third beginning in 2003. During the 1970s and 1980s, Chrysler also used the Hemi designation for the four-cylinder Mitsubishi 2.6L engine.

How to Super Tune! Performance Engine Building and Carburetor TuningReviewsThis video is great! It has lots of info and is easy to go back to review sections,or just watch the whole dvd again. I guaranty you'll pick up something new every time.Winter is here, the drag strip is closed,this would make a great gift for any performance enthusiast on your list. the dvd was well planned and easy to understand and follow with its contents leaving little question on what to do. Produced results that went far beyond I ever thought I could get out of my car. Recomed for all to use This DVD is GREAT. Wayne tells you the ins and outs of building a SUPER PIMP motor. He is Very knowledgable and knows what he is talking about. Everything you need to know is in this video. He explains things very well and in depth. After watching the video, I had a few questions. I was able to call Wayne and talk to him, and he was more than happy to answer my questions. You can definently tell this is not just a job, its his passion. I would recommend this video for anybody who enjoys GOING FAST and BUILDING IT RIGHT THE FIRST TIME..... PVP It's obvious that lots of thought and planning went into this DVD.

A lot of the terms and techniques used in engine building were REALLY explained to me for the first time! A first-class video. This comprehensive video should be in every car nuts collection. Whether you're a drag racer looking for that next tenth, or just want the most power out of your street combination, this video will deliver the goods. Average Rating:  |

Big Block Mopar Performance - High Performance and Racing Modifications for B & RB Series EnginesReviewsgreat source of information from one of the best engine builders in the country. Whether you are building a street motor or race motor this book will help with your engine build. First, I own many books viewed as competitors or complements to this book. This however is my favorite so far. Why? Well to start with the information tends to be an excellent blend of general how and why the individual engine components work and the effect they have in contributing to the overall performance and attitude of the engine you are building. The book really comes through with some very specific recommendations on part and process selections. The author authoritatively speaks to some of the well-earned reputation, legend and mythology of the mighty big-block Mopar engine family. The book guides the reader through, not merely choosing between stock or all-out-race, but acknowledges the deisre of most enthusiasts to be somewhere in between. lots of info and history of the engines. Also gets onto the the area of what is best of MOPAR and aftermarket equipment. Chuck Senatore's new book on building high performance Mopar B & RB motors is well-written, with excellent tips and advice for the hands-on home builder, or the professional engine builder. His experience with building Mopars, and with helping to develop his company, Muscle Motors, into a respected authority on Mopar engines, is evident throughout. While this is not a step-by-step engine building guide, it provides background for all the decisions that must be made before one begins the building process. Particularly valuable is the discussion on developing a plan and purpose for the motor you want to build, before starting. The only criticism I have of his information is that it seemed he gave short shrift to head porting, and hydraulic cam choices. Though home head porting is one of the hottest, and simplest, mods a competent novice can perform, Mr. Senatore devoted less than a page to the actual process, and recommended the novice leave this job to a machine shop pro. Little more time is spent in the discussion of hydraulic cam choices for hot street performance, even though this is the major growth and interest area for Saturday night street cruisers which see little actual strip action. For the person who is interested in these areas, there are pleaty of information sources elsewhere, and I still believe that this book is a must for any person who is considering building a B/RB motor, regardless of their level of experience. Good job, Mr. Senatore! Average Rating: |

Hundreds of thousands of racing enthusiasts rely on this essential guide for building a race-winning, high performance big-block Mopar. Includes detailed sections on engine block preparation, blueprinting and assembly. |
A hemispherical (i.e., bowl-shaped) combustion chamber allows the valves of a two valve-per-cylinder engine to be angled rather than side-by-side. This creates more space in the combustion chamber roof for the use of larger valves and also straightens the airflow passages through the cylinder head. These features significantly improve the engine's airflow ("breathing") capacity, which can result in relatively high power output from a given piston displacement. With a hemi combustion chamber, there is minimal quench and swirl to burn the fuel-air mix thoroughly and quickly; the spark plug is frequently located at or near the centroid of the chamber to facilitate complete combustion. Engines with hemispherical combustion chambers often use dome-topped pistons to attain the desired compression ratio.
The hemi head requires intake and exhaust valve stems that point in different directions, requiring a large cylinder head and complex rocker arm geometry in both cam-in-block and overhead cam engines. Hemipsherical combustion chambers lack the quench area found in wedge combustion chamber designs, making the hemi more sensitive to fuel octane; a given compression ratio will require higher octane to avoid ping in a hemi engine than in a wedge engine.
