Here's 5 reasons why pushrod engines still exist, while checking out a 3D printed V8 engine. Pushrod engines typically use two valves per cylinder, and as a result this engine style is often mocked when used in modern vehicles. Fewer, larger valves results in more reciprocating mass which can lead to valve float, and less airflow at high RPM from the reduced area of the valve openings versus four valves. So why are companies like Dodge still making Hemi engines, and Chevy still making LS engines

This is CGI . The formidable Hawker Typhoon Mk 1b, with its Sabre engine roaring to life in weather test conditions! Achieving the rain and fluid dynamics effects in CGI was a real battle, we nearly fried another computer in the process but every attempt is a lesson. We’re thrilled with the results, the Typhoon looks fantastic in the rain, framed by the blister hangar behind her. | SpitfireCGI
