It looks like they are bringing back the 5.7 Hemi. This would be an excellent opportunity to make some upgrades that I am calling the 5.7 Hemi Heavy Duty. Most of the upgrades can be done with existing Mopar parts. This would make a bullet proof 5.7 Hemi. See what you think below.
There are rumors that Mopar is working on an overhead cam V8. The advantage of an overhead cam engine is that you can control the cam timing of the intake and exhaust separately with individual cams. Something I learned from
Reignited Cycle and Automotive YouTube site is that this can be done without having separate cams for the intake and exhaust (

Personally, this seemed to be a much better approach that keeps the identity of the Hemi rather than an overhead cam engine.
5.7 Hemi Heavy Duty (HD)The majority of these parts come from the Mopar parts bin.
6.2 Hemi stock forged crankshaft (same stroke as the 5.7 Hemi)
6.2 Hemi stock forged connecting rods
Forged pistons – 5.7 Hemi pistons are smaller than 6.2 pistons – vendors Mahle, Wiseco, Manley
6.2 Hemi oil pump or better yet the Melling 10452HV
6.2 or 6.4 Hemi Exhaust manifolds
Camshaft material upgrade – Cam within a cam controlling the intake and exhaust separately made of a billet core or other materials more durable than stock camshafts
Camshaft Lifters – Johnson Lifters
