2015 6.2 Hellcat Factory Cam

Factory 5.7 valve springs are definitely not strong enough to support a big cam like the hellcats. That said, the valve to piston clearance more than likely isn't either.

Naturally aspirated 5.7? If so, you'd be much better off using a stock 6.4 cam

I thought Greg did this and it showed hp on the dyno but not at the track in his times.

The 6.4 cam, with its long LSA is a nice little blower cam providing you have the supporting mods. This is true of almost any cam upgrade, you need the supporting mods to make it work well.

 

That being said, a custom grind is the way to go.
