It’s for the ones who disputed our Episode 2 test with throttle-body injection (TBI) not being real electronic fuel injection (EFI). So we’re back and more serious than ever with a state-of-the-art 1,050-cfm multipoint EFI system facing off against the 750- and 1,000-cfm relics known as carburetors. Which will squirt the most power into our tried-and-true 383 Chevrolet? Find out here.
