It’s our first head-to-head shootout with two engines: a Blueprint Engines crate Chevy 383 small-block versus a hand-built Mopar 383 by Engine Masters host Steve Dulcich. To make this a fair test, we equalized as many variables as possible: both engines use the same carburetor and the same type of ignition, intake manifold, camshaft, compression ratio, oil pan, and oil. Both use the best iron cylinder heads available from the OE manufacturer. So what’s your guess? Which engine will make the most average horsepower and torque? Find out the surprising answer and have some fun with David Freiburger, Steve Dulcich, and Steve Brule in this episode 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.
