Due to the latent heat of vaporization a carb'd motor can make like 2% more power at max output. The cooling of evaporating gas does it, which helps air density. The EFI fuel doesn't boil until in the cylinder, but conversely that reduces the chance of detonation.

2%, or even 5%, at wide open peak output only should matter only to heads-up drag racing, really...

If you want a carb, get a carb, none of my business. I just want to disabuse anyone from the notion that the car will be faster, better, stronger, or really in any way improved by a carb over EFI.
