With all the injection bits installed, the engine once again leaves the test stand and makes its way to the dyno. Wearing the 21st-century self-tuning kit, the engine puts down 295 horsepower and 329 pound-feet of torque, making for a gain of 13 horsepower and 16 lb-ft.

The 1,100- to 1,300-cfm dual carbs are good only over a narrow range, about 1,500 rpm at most. EFI performs well over 2,000 rpm or more. On average, if optimized, both systems perform about the same as far as how fast you get down the track. However, the EFI system is much easier to tune than a carburetor.

The carburetor regulates the air-fuel mixture by means of suction while an EFI system is able to deliver a much faster and accurate response through the use of injectors. EFI systems are able to run more efficiently and effectively which means fewer emissions and better fuel economy.

If you're looking for more reliability, efficiency, and accuracy, then EFI may be a good option for you. However, if you're looking for that old school muscle feel, less complexity, and something little more cost effective then a carburetor is the way to go.

EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. They optimize air/fuel ratios and ignition timing while compensating for other factors to maintain continuous optimum performance.

The carburetor provided charge cooling, and with a little more carb work on the metering blocks and booster design, might just provide more power through the entire curve compared to port EFI.

Increased Reliability EFI systems maintain optimum air/fuel ratios, eliminating random engine stoppages, oiled spark plugs and other problems associated with sub-optimal ratios. Carburetors tend to need frequent adjustments; EFI engines eliminate the need for repeated modifications.

EFI systems are able to run more efficiently and effectively which means fewer emissions and better fuel economy. Because fuel injection is more accurate, it is also said to be more powerful as well. EFI systems can account for changes in the atmosphere, air, and fuel while carburetors aren't as accurate.

Many people choose to make the switch from a carburetor to EFI because EFI systems tend to be more reliable. This is due to the fuel being injected into the engine under pressure which makes for a consistent air/fuel mixture.

The carburetor regulates the air-fuel mixture by means of suction while an EFI system is able to deliver a much faster and accurate response through the use of injectors. EFI systems are able to run more efficiently and effectively which means fewer emissions and better fuel economy.

Disadvantages of fuel injection Substantially more expensive than carburetors. · Cannot be repaired with simple tools, have to be replaced, which is expensive. · Cannot be customized, unless you go for custom ECU maps, which again is expensive.
