Deciphering The Differences In The Chevy 2.2L Engine
Since its birth in 1990, when the old Chevy 2.0L engine was upgradedwith a stroke increased from 3.15? to 3.46?, the 2.2L powerplant hasbeen upgraded several times: the block has been revised four times andthe head has been changed three times (it was discontinued after 2003, replaced by the 2.2 L Ecotec). Let’s start in
Close-Coupled Converter Caution on Late Model GM Vehicles
This new style converter provides quick catalyst warm-up, resulting in lower tailpipe emissions earlier in operating cycle. If and engine failure (such as a broken intake/exhaust valve orpiston), debris may be deposited in the converter through engine exhaust ports. If the engine failure is due to a severe overheating event, damage to the ceramic “brick”
Sportsman Drag Racing Engine Rules
Dragracing – lining up next to the other guy and seeing who’s got the beststuff – remains an incredibly popular sport, for both spectators andparticipants. Although multi-lap circle track and road racingcompetition may have received the lion’s share of media attention overthe past several years, mashing the throttle and driving to the finishline is good

Use New Head Bolts In Your Rebuilt Engines How much pressure is exerted on a head bolt? In a typical V8 engine, peak combustion pressures could be around 1,100 psi, which means each cylinder exerts about 14,000 lbs. of pressure on the cylinder head at full throttle. In fact, each head bolt may have to
A Closer Look at BBC Bracket Racing Cylinder Heads
However, it proved to be just the opposite – sportsman racers loved it and it allowed local drag racing to thrive and grow. Back in its infancy, I covered weekly bracket racing in Southern California at the now defunct Irwindale and Orange County International Raceways. The action was hot and heavy with full fields of
CNC?Head Porting & Machining Centers
The fact that CNC machines have come down in price over the years, coupled with less complicated interfacing systems means that today they can be used by nearly anyone. You don’t have to relearn everything. You don’t have to take endless courses on how to make a tool change. Today’s machines are sophisticated and savvy
Street Performance Cylinder Heads
Where I grew up in Connecticut wasn’t the hotbed of street racing like Woodward was in Detroit, but we had the Berlin Turnpike, River Road in Middletown, plus a few local small-town hotspots. It was during this period that I got my first education about the importance of cylinder heads. A local rich kid got
Performance Marine – Is It the Last Engine Frontier?
It is said to be one of the last great open frontiers. Many experts say that it’s just about the last place on Earth where there are no rules to confine speed or size. It’s a place that has lured men with adventure and danger for centuries and now may be calling you, the engine
CFM Rules
CFM and Carburetors: Carburetors are rated by CFM (cubicfeet per minute) capacity. 4V carburetors are rated at 1.5 inches (Hg)of pressure drop (manifold vacuum) and 2V carburetors at 3 inches (Hg).Rule: For maximum performance, select a carburetor that is rated higherthan the engine CFM requirement. Use 110% to 130% higher onsingle-plane manifolds. Example: If the
Small Block Chevy and Ford Performance Cylinder Heads
Over the years, the SB Chevy V8 evolved and grew in displacement from 265 to 283 to 302 to 327 to 350 to finally 400 cubic inches. Aftermarket blocks and stroker cranks have allowed even more displacement, with some “small blocks” now having as many cubic inches as a big block Chevy (427 and 454
Kicking Asphalt
In this election year it somehow seems appropriate to talk about a movement that reaches the common citizen…the working man…the small-business person. Political rhetoric aside, it has the potential to gain traction in the industry and showcase what’s great about America – grassroots road racing. There are no multi-million dollar sponsorships (multi-million dollar wallets not
Taming The New Tiger
Say the name Arnie “Farmer” Beswick and many an old Pontiac fan will nod and share a story or two about Arnie and his legendary GTO, the Tameless Tiger. About two hours down the highway in Illinois, Jim Riskovsky, owner of Turbo Connection in Edwardsville, IL, is learning to tame his own tiger, his 2005
Choosing A Replacement Camshaft
Unless you are doing a totally stock rebuild and reusing the original camshaft, selecting a camshaft depends on what kind of engine you are building and how that engine will be used. A stock engine for a daily driver is obviously an entirely different application than an big stroker motor for a Pro Stock racer.
The Shermanator 347: A 530HP Gas Stroker You Can Build
A while ago Engine Builder ran a story on the popularity and basic dos and don’ts of stroker engines ( March 2007 Engine Builder). It received such great response that we are following up with a “real world” stroker engine buildup. In this case, it is an engine combination that is so popular that it
GM’s 6.5L Diesel Engine
The 6.5L GM diesel engine was introduced in 1992 to replace the 6.2L diesel engine and was in turn replaced by GM’s Duramax 6600 in 2001. On the surface it would appear that the story of the 6.5L diesel would end here, right? Well, that wouldn’t make much of an article. In actuality, production of

The AERA Technical Com-mittee offers the following information regarding exhaust manifold bolt and torque update on 1998-2003 GEN III 4.8L, 5.3L, 5.7L and 6.0L engines. A new exhaust manifold bolt and torque specification was introduced to the GEN
Wet Flow Testing
Racers and engine builders are familiar with flow testing, used to measure the airflow and efficiency of their cylinder heads. In theory, there are two basic aerodynamic factors that are intuitive in the human mind. Number one, a bigger hole will flow more air. Number two, a smoother hole will flow even more air. To
Which Cranksfaft Meets Your Racing Needs Best?
There are a lot of racing crankshafts in the automotive aftermarket today. You’ll find a wide variety of styles, strokes, weights and price ranges from which you can choose. The question you need to be asking is which crank is “right” for the engine you’re building? The answer to that question depends on several things
Researching the Rebuilding Market for Multi-Valve Cylinder Heads
Cylinder head work has provided a good income for many of our readers over the years. All engines eventually need a valve job and guide work if they accumulate enough miles. Head work may also be needed if an engine overheats and blows a head gasket, if the head develops a crack, or an OHC
