Speaking from a pure swap standpoint, EFI is just better. In our 64' Falcon, we had a 289 carbed, a 302 carbed, and now a 5.0 EFI, and make hands down way more horsepower than I did before.
88' 5.0 H.O. (throttle body to pan) $150 -Craigslist
91' A9P ECU + wiring harnesses and relays $50 -Craigslist
96' Explorer (GT40) heads, intakes, TB and 19# injectors $125 -UpullRparts, Rosemount, MN
.030 Milled, 3 angle valve job and new seals $300 -Cylinder Head Supply, Minneapolis, MN
Crane 1.7 RR $120 shipped -Craigslist Cincinnati, OH
Trick Flow Spring kit $150 -Summit Racing
94' Lincoln Town Car (F2VF) MAF $15 -Highway 101 salvage, Savage, MN
MSD external fuel pump $65 -eBay
20' Braided line, fittings and clamps $200 - Jegs
So for a grand total of a little over $1100, I went from a 79' carb'd 302 to basically a 93' Cobra setup. I have since sold the 79' block, cam, heads and the 88' E7 heads and H.O. intakes, injectors, TB, and MAF for a total of about $500, and I still have in my possession a 289 Performer intake, edelbrock 600cfm carb, manual fuel pump, air cleaner, etc., which is everything I need to have to go back to carbed if need be. I'd imagine once I'm done with this motor, I would easily be able to recoupe my money that I've invested.
I don't know much about carbs other than it is a controlled fuel leak. I was born in 86', so I grew up with fuel injection, and more importantly a digital voltmeter. I can diagnose my own EFI system very easily as I was the one who imagined it, created it, and installed it. I understand how to tune a carb, but there is something that can be said for 95% of racing teams use some sort of electronic fuel strategy. I completely and fully agree that ford's EEC-IV isn't very friendly to hotroders, but it is the ease of the swap that makes the ECU so great. Both carbed and EFI have their ups and downs, but to me, I would never go back to a carbed setup just because of the driveability, fuel economy, etc., and at the end of the day, I would be happy to pay a little more to have the reliability of the 5.0 EFI setup.
