With a winter chill finally settling over us here in Virginia, I spent a good portion of this week under a warm blanket reading about Spring projects. More specifically I was taking in Tony Candela’s EFI Conversions, How To Swap Your Carb for Electronic Fuel Injection. Prior to picking up EFI Conversions I wasn’t familiar with Candela, though after reading it I ordered two more of his tech books. Candela has a gift for explaining complex technical subjects, illustrated with clear, logical, full-color photographs.
If you’re not already familiar with the benefits of Electronic Fuel Injection, Candela will lay it out for you. Better fuel economy. Improved drivability. Endless tuning opportunities. He also covers the basic principles of EFI operation and tuning as well as common EFI systems, and how to choose the right system for your vehicle.
EFI Conversions isn’t all theory though. Candela documents the installation of three different EFI systems. He installs a Holley HP EFI system on his own 6-71 blown big block Chevy powered Cutlass, an MSD Atomic EFI system on a stroked small block Chevy, and a Holley Dominator system on a 455 Olds. Each project is laid out in detail, outlining pre-planning, installation, tuning, and troubleshooting.
While all of that is good, what I most appreciate about EFI Conversions is the fact that Candela takes the time to address each vehicle’s shortcomings to ensure every installation is a success. This isn’t a glorified Holley handbook. Candela explains in detail how to ensure your car’s electrical system is up to snuff before adding the additional load of electric fuel pumps, fans and controllers, how to properly plan and assemble an EFI fuel system, and more. As an added bonus, Candela includes photos and explanations of the updates he made to the featured vehicles’ fuel and electrical systems prior to completing the EFI installations.
EFI Conversions, How To Swap Your Carb for Electronic Fuel Injection is among the best written and laid out technical publications I’ve read. Though an EFI conversion is not on the table for my car in the near future, I will anxiously await the opportunity to put my newfound knowledge to practical use.
