Everyone wants EFI for their classic rides, but the choices can be confusing. From used stock parts to high-zoot laptop-tunable systems used on 6-second racecars, the decision can be migraine inducing. The folks at Fuel Air Spark Technology [www.fuelairspark.com; (877) 334-8355] are aware that people want bolt-on simplicity with all the benefits of EFI and have introduced a new EZ-EFI system as an answer. The EZ-EFI bolts to any 4150 Holley-flange-based carbureted intake, handles up to 550hp applications, uses a wide-band 02, and the included electronics are self-tuning. Bolt it on and drive for under $2,000.
