Engine Masters

In this first episode you’ll find out if Blueprint Engines is accurate in its advertised power for a 400ci Chevy small-block crate engine, and then we’ll see if Freiburger is justified in his love for dual carburetors and high-rise tunnel-ram intake manifolds—plus there’s cash on the line. In upcoming episodes you’ll see carbs versus EFI, Chevy versus Mopar, Edelbrock versus Holley carburetors and lots more. Come back to the Motor Trend channel of YouTube or to MotorTrendOnDemand.com for more of Engine Masters, presented by AMSOIL.

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. But if you’re a carburetor guy considering your first foray into fuel injection, this episode of Engine Masters is for you.
