    1. Imagine how much it would not. EFI gives you better drivability…you can change altitude easily. But as far as max HP goes it does not make a difference and when you go with “bigger” cams most EFI can’t handle the rough low RPM idle. Nascar engines have carb restrictions in place to keep the power down…
