Has anyone tried one of those bolt on fuel injection units yet? They just bolt on like a carb. I see ads in car magazines all the time. I see Edelbrock and Holley make them. They are supposed to be easy to tune and can handle big horsepower. How well do they work?

 

I am interested in the same thing, they seem pretty strait forward. I am helping a friend install one on his car, the install is pretty easy so far but we will see in the end. This unit is being installed on a project car so it may take some tine until we get to the fire up phase. I am debating putting one on my 68 Camaro, it would be nice to get a little better/easier start ups and easier fuel economy. Its just a little bit costly in the begining and if I have to run a return line then theres that so...

 

I also thought it was a good idea at the time --BUT at 2k$$ i can buy a lot of gas as the diff in gas mileage isn't that greater?? Maybe more power but not much --so i kept my Eddy carb!! Just my humble opinion!!

 

There are pros and cons to both carburetors and fuel injection.

Carb. pros:
simple, inexpensive to maintain/repair for a Q-jet or Edelbrock (Holley I seemed to get 1 in 10 that would keep a setting)

Fuel Injection pros:
easy starting in all weather conditions, better fuel mileage, better overall performance

Carb, cons:
can be tempermental at times, dead spots on accel at times, susceptable to fuel foaming/vapor lock with ethenol fuels, poor fuel mileage

Fuel injection cons:
hard to diagnose for the average person, costly for the average person, can be hard to "dial-in" for higher hp engines for the novice

With all that said, I like carb equipped for the average personal daily driver with a simple carb like a Q-jet if you're on a budget. If you have the $ go with the fuel injection. You can't go wrong with a properly installed system. The performance of the car will be drastically better than a carb equipped one.
