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.
You can’t throw a stone these days without hitting an aftermarket aluminum cylinder head. They perform as good or better than anything the factories put out, and then some. They are much lighter than iron heads, and they’re now extremely affordable. Thanks to competition in the aftermarket, it could easily be said that for the performance and price benefits of a new set of aluminum heads, why would anyone bother refurbishing a set of iron castings?
This is the problem in a nutshell: When we are traveling in an automobile, it may seem that we personally are not moving, only the car is. But that is not the case. If the vehicle that we are traveling in happens to stop suddenly, we won’t, unless … there is something there to stop us. That something could be a seatbelt—or it could be something less desirable.
The cold hard fact is that injuries can be suffered during an auto accident. Injuries such as those sustained by the face and head as a result of being thrown into the windshield or dash. Or it could mean those nasty abdominal injuries due to contact with the steering wheel. Either way, it doesn’t sound like much fun. They can also be prevented.
All of your hard work and efforts could go up in smoke before you have a chance to do anything about it. That is, unless you have a quality set of gauges to monitor initial and ongoing engine parameters. Gauges allow you to know exactly what is going on within your engine at a glance. Is the oil pressure too low? Is the engine running hot? Is the battery charging?
Some Years Ago, Chevrolet Began Lowering Engine Compression (To 8.50:1) In An Effort To Meet Tailpipe Emissions Numbers. It Also Retarded Camshaft Timing In An Effort To Lower NOX (Nitrides Of Oxygen/Unburned Particulates). By 1974, Horsepower, Torque And Overall Engine Efficiency Had Dropped Some 30 Percent To 50 Percent. Chevy’s RPO L48 And LM1 350 Small-Block V-8s Then Got A Flow-Restrictive Catalytic Converter In 1975, And Finally In 1985, A New Monolith Catalytic Converter, As Well As Direct-Port Fuel Injection And Improved Camshaft Timing, Boosted Horsepower, Torque And Engine Efficiency.
