I want to add my voice to those who like fuel injection.

There are 3 types right? Speed Density, Alpha-N and Mass Air Flow. (I'm ignoring mechanical FI)

One of the last hot rod projects I was involved in, quite some time ago now, was the retro-fit of a Ford EEC-IV fuel injection system into a classic Mustang. This was before kits to do so were readily available, I helped the owner "roll his own" using many parts salvaged form the used auto parts emporium (wrecking yard). The system was literally plug and play. We installed the parts, engineered the wiring, installed & hooked up sensors, turned the key and the car immediately started and ran like a car with fuel injection, where as the last time the car had ran, it ran like a car with a carburetor. What a difference! This experience made me a believer.

The Alpha-N boxes and Speed Density boxes that were sold with many aftermarket fuel injection systems in earler times I believe were poorly engineered, too primitive, or possibly they just didn't consider who the end user was, what ever the case, many people purchased them and could never get them tuned properly so they gave up and went away with a bad attitude regarding fuel injection. I believe the latest generation of boxes on the market are much better in that respect. I have seen in ad copy from each manufacturer where great attempts have been made to make their systems more "plug and play", i.e. more user friendly for the less than technically astute end users.

If you want easy to install fuel injection my recommendation is a Mass Air Flow system using Ford EEC-IV or EEC-V electronics. Of course, those folks wanting the independent runner look, must resort to Alpha-N or Speed Density controls.

Whether we are talking carburetors or fuel injection, many people including myself have found aftermarket independent runner systems to be "fussy". However, I have worked on & been around motorcycles for over 4 decades that almost always use independent runner intakes, whether they have 1, 2, 3 or 4 cylinders, and they have ALWAYS run perfectly BITCHEN from idle to very high red lines. In all weather, all year 'round, and over a wide range of altitudes, they start & pull with out a hitch throughout their power bands. So indepenent runner systems can work, IF they are engineered properly.

And they certainly look bitchen!
