Do anyone know who makes the best EFI carb ?

 

First, the term "EFI carb" is an oxymoron. I assume you are asking about a throttle body EFI system.

Second, "best" in what way? Max performance? Best gas mileage? Easiest to program? Easiest to install? Cheapest?

Third, what car, what engine, and how will it be used?

 

Performance all way around I hear holley is the best I'm putting it on my 72 cutlass 350 olds and I'm going to go with a 2004r tranny are 700r4
