5.7 Hemi Heavy Duty (HD) vs Overhead Cam Engine

Interesting topic. Reality for me is, it will not be in any foreseeable budget of mine haha... well, I guess I am hitting the lottery soon, so there's always that.

When I see these youtubes, speculating so many different things, I always ask myself.. how much is this gonna cost if it actually does happen? Then I start thinking about how it will be before aftermarket follows. If you thought a gen 3 Hemi swap was expensive...
