Mopar Insiders has posted a video claiming that FCA has shelved plans for the 426 engine. In its place will be a twin-turbocharged inline 6 cylinder engine making 360 hp. An HO version will make 525 hp. They are expected to go into production in 2023. If this s true, hang onto your 5.7, 6.1, 6.2 and 6.4 Hemis. It looks like the days of the Hemi may be numbered.
