Engine Masters

Experts test a 400ci Chevy small-block crate engine to see if it lives up to its advertised power. Further review will determine if David is justified in his love for dual carburetors and high-rise tunnel-ram intake manifolds.

The guys strap a 5.3L LM7 engine to the dyno to see how the new easy and self-learning EFI setups compare to carburetors for price, installation and power.

In a head-to-head shootout with two engines, a Blueprint Engines crate Chevy 383 small block takes on a Mopar 383 hand built by host Steve Dulcich. To make this a fair test, the crew equalized as many variables as possible.

The guys see how dings and dents to a engine's headers can affect horsepower.

The guys try to get maximum horsepower from a stock, bottom-end 5.7L Dodge Hemi.

The guys figure out how much of a difference CNC ported cylinder heads make for people who are running a typical street-cruising small-block Chevy V8.

The crew compares the price, tune up and power of the Holley Tri-Power setup to the Edelbrock Performer RPM Dual-Quad manifold and carb kit.

The crew tries to boost a Dart SHP 363 cubic-inch Ford engine using two different superchargers from Weiand and Paxton. They'll share all the installation details, problems and, of course, the power curves.

The crew explores the differences between 2.5 and 3-inch exhaust for power, tuning and weight.

The guys explore how hydraulic roller lifters differ from more race-ready solid roller lifters.

Experts take steps to find out which engine dominates with a dyno duel between Mopar and Ford.

The guys determine how to pick the right sized exhaust header tubes for your engine.

The guys show how nitrous oxide increases horsepower and give tips on how to use it safely.

The guys show why putting speed parts on a used engine from a running car might not be a great idea.

The guys test cast manifolds and mid and long-tube headers to see which is more powerful.

The guys spell out the differences in two camshaft designs so you can decide which is best.

In this episode, we explore whether the price of a muffler makes a difference when it comes to performance. We provide dyno-proven answers as we run all the tests with a perfectly average 350ci small-block Chevy using Thrush and Magnaflow mufflers.

Increasing engine displacement with a stroker kit is a proven way to get more horsepower and torque, but exactly how much power? In this test of "there's no replacement for displacement," the hosts run a dyno compare you've probably never seen before.
