I would buy a 6.4 short block cam and all and stuff it under you heads. The OE 392 short block is about the same prce as a rotating assy to stroke a 5.7 and all the machine work and assembly is already done.
I have seen broken valve springs on the eagle 5.7 and a bunch of flat cams.

If your going to get a block(6.4, Hellcat) go 426, 4.05 stroke with the 4.09 bore, and don't look back. As for cam inertiamotorsports.com tell these guys what your looking to do and they'll help you with a good tow haul cam.
I have 426CI 6.4 with Eagle heads in my 2014 ram right now, , pulls like a V-10 , gobs of low end break stuff type pull. I had 392 with eagles and a SRT 392 Auto cam in it, ran great but no bottom end, the cam didn't like that off idle pull, even with the stock Eagle intake.

So the 6.4 with a SRT 6.4 cam didn't have TQ but the 5.7 you swapped on into did? If towing was my only goal I would probably use the eagle cam and heads on the 6.4 short block. My 2011 5.7 tows my open car trailer with a mid size car on it pretty awesome, I pass 12 valve cummins trucks with similar loads on the big mountains around here pretty regular. It does need to turn more RPM but so what, it don't seem to hurt anything and turns in 13mpg while towing on a regular basis.

I would think that smaller ports and a milder cam would be the hot ticket for towing... I'd get a cam recomendation from Mike Jones at www.jonescams.com. He will sell you a new cam or regrind your stocker... smart guy.

5.7 ? the only 5.7 that was in the truck was the stocker, I put a SRT 392 cam in it(the stock 5.7) back in March, , lost some low grunt, not notable unloaded, but with the trailer and my Niece's 2010 challenger , you could tell the difference. That 5.7 has been out of the truck since late May early June
What I was talking about in my org post was stock SRT392 auto (6.4 Short block) vs 426CI Hellcat block, both had the same set of Eagle Heads on them,, but different cams. I have the stock 5.7 cam in the 426 right now. Very little tuning has been done, and this truck still has the stock manifolds and exhaust.
