Sort of? The truck V10 was in the works before the Viper was a concept and it started as a 5.9 with 2 more cylinders. But look where the truck V10 ended design wise. It really doesn’t share much with the Magnum beyond maybe the piston design. No distributor, symmetrical ports and it even looks like they corrected the wonky pushrod angle.
And after the Viper team got done with the Viper V10, there isn’t anything shared with the truck V10 beyond maybe some bolts.
But yes, it is a pushrod motor. I think the LS/LT and Godzilla have proven there is still potential. And the designs are already done for the most part so (in my mind) the development costs to create a new V8 would be much reduced, it might be cheaper overall than the Hemi and the emissions would probably be better.
Just a fun idea, nothing I think the factory would entertain.
