Engine Masters

The Mystery of the Great 4/7 Swap (5x9)

Date de diffusion: Avr 24, 2020

On this episode of Engine Masters, presented by AMSOIL, we put more power claims to the test! This time it's the belief that a simple swap of the standard 1-8-4-3-6-5-7-2 firing order can create more power in your 90-degree V-8. Whether it's changes in manifold pulsing patterns or crankshaft harmonics that make more power, the theories abound. So we're here to do a 4/7 swap on a big 572 to see if there's more power to be had or if the theories are just that: theories.
