(1989 5.0 Carb. Swap) What Dis. To Use - StangNet.com
Carbs are great for the track and make good power. EFI RULES on the street for a car that is driven in all kinds of weather, up and down mountains and gets great gas mileage. EFI will make just as much power as a carb and be easier to drive on the street. There isn't a carb made without computer assist that can do all those things as well as EFI can. The only possible exception would be the IDA or DCOE Webers which cost major $$$ - like $3000 for 4 each IDA 48's and a manifold. Here's a book that will get you started with how the Ford electronic engine control or "computer" works. Ford Fuel Injection & Electronic Engine Control 1988-1993 by Charles Probst: ISBN 0-8376-0301-3. I suggest you Google the title and see who has one for a reasonable price. A word of warning on EFI to carb swaps: don’t expect to pass emissions in any state that does comprehensive smog inspections, because it won’t happen. Some states will not title or issue license plates to cars that have been converted from EFI to carb. If you operate the vehicle on public highways and get caught by state or federal law enforcement (doubtful, but possible) you could be subject to fines and imprisonment. You won't get any more power from a carb than you will from EFI. Source: www.stangnet.com
