Sequential-Port EFI for your Classic!
Pro-Flo 4 EFI Systems from Edelbrock is the latest generation of fully sequential port self-learning electronic fuel injection. Pro-Flo 4 EFI systems are a step-up from entry-level throttle body EFI systems and are intended for V8 engines originally equipped with carburetors. Each system features an all-new ECU with a faster processor and waterproof design, and an advanced tuner that gives control over air-fuel ratios, ignition curve, idle speed, acceleration fuel, coolant fans, and rev limiter. Edlebrock Pro-Flo 4 EFI systems retain the simplicity that Pro-Flo systems are known for but deliver more accurate, and precise performance output, all without laptop tuning.
