The cross-plane V8 is a great engine configuration thanks to its balance, compact dimensions and power potential. Jason Fenske from Engineering Explained has explained the beauty of the motor with a 3D-printed Chevy LS3 engine. He has demonstrated what goes on inside the traditional engine. A V8 with a cross-plane firing order has one cylinder firing for every 90 degrees of crankshaft rotation. This means that two cylinders are on the power stroke at any time. According to Fenske, this is the reason for the smooth power delivery for which V8s are famous.

The LS3 engine which is used here is one of the most simple of modern V8s. The knowledge he has shared here also applies to other V8s too. Most of the V8 engines that you see use a similar cross-plane layout. Fenske has also explained what makes a flat-plane V8 engine found in Ferrari, McLaren supercars and Ford Mustang Shelby GT350, different from a cross-plane engine. Here is the video that explains the functioning of this amazing engine.
