Fuel Injection

[eschaider]

Ray,

I think it comes down to a matter of control and tunability. The electronic fuel injection gives you both in spades. Unless you are very familiar with things like emulsion tubes, air bleeds and venturies you will be at a disadvantage replicating the tune you can quickly come up with for your engine with electronic injection and your laptop.

From a power standpoint I am not persuaded the injection outperforms properly set up carburetors. From a cold start and cold weather start standpoint the injection is clearly superior. In terms of A/F ratio maintenance electronic fuel injection has no equal which is why Detroit went that way to meet federal emission standards. An interesting add-on benefit is potentially better fuel mileage.

The engine's dirving manners will improve somewhat if you have a large cam because the fuel delivery will no longer depend on a weak vacuum signal at low engine speeds. You may also discover that you pick up a couple hundred of additional usable rpm at the bottom of the RPM range. Always nice for highway cruising if you have one of the overdrive 5 or 6 speed units.
