Engine Masters — Season 1, Episode 2: Carburetor vs EFI Shootout!

Episode synopsis

Should you run a carburetor, or should you try the new and easy self-learning EFI setups? We'll dish up answers in this episode of Engine Masters, presented by AMSOIL. Host David Freiburger, Steve Dulcich, and Steve Brule strap a 5.3L LM7 engine to the engine dyno and look at the price, installation, and power of a Holley 750-cfm double-pumper versus Holley's Terminator throttle-body EFI. The guys come up with a big part-mismatch nightmare along the way-one you should also watch out for. As you're watching the episode, keep in mind that most of the carb-vs-throttle-body info applies to any engine, not just the LS-style test mule. However, Holley does provide very simple, plug-in kits to power the LS platform. In fact, if you have a complete junkyard LS that still has the intake manifold, throttle body, and injectors, you can get a much cheaper LS controller that plugs right in.
