If you're talking about those old MM&FF or 5.0L & Super Ford's tests that were done years ago in their magazines, I remember them. I also remember a very bias comparison and although the carbureted cars made more horsepower at peek, the EFI cars made a pile more horsepower and torque under the curve.
Anyone who believes carburetors are superior to fuel injection needs to have their heads examined. They come from an era where 90% of the cars on the road had an old Rochester or Holley on them and refuse to change with the times no matter how often they get beat. Most of these guys are the same ones who think an aluminum intake an off the shelf "lumpy" cam and long tube headers will cut 2-seconds off of their ride and eveyone who'se got them automatically makes 350hp and above. These are usually the same kinds of guys that believe the old gross horsepower rating used in the 60’s and SAE net and RWHP are all the same figure.
A prime example is the Boss 302. It was one of the baddest cars of the 60’s and 70’s and was commonly known to be “underrated” horsepower wise from the factory for insurance purposes. Most guys of that era are still under the impression that the Boss is still a faster strait line car than all but the most serious high dollar machines on the road to day. When I reality, a stock '87-'93 Fox body would easily outrun it.....and I mean bone stock! Hell, even a 429 Boss has trouble hanging with a Fox body with a gear change and a few basic bolt ons.
The Carburetor is a dinosaur compared to EFI. Poorer emissions, lousy cold start, lesser fuel mileage.....just plain over all inferior efficiency in general. They’re good for a racer who’s starting their build from scratch on a budget, or for someone who refuses to get with the times and step out of the dark ages and knows nothing else but swapping jet sizes and screwing with float levels or idle air screws, but for anyone else it’s just impractical!
