Are hellcat pistons 2618 material?

This question came up on Facebook recently.  What type of forged pistons are in a Hellcat?   I know the rods are " powder forged"  but what about the pistons?  Would they be good for a power adder build?

Thanks.  Has anyone heard of a Hellcat PISTON failure?  I know that rods have let go but what about pistons?



Mahle makes a great replacement piston to bump stock CR to 10.5 and Carrilo makes a high quality rod that can take a beating.

Next up is cranks, haven't found a good price on one. If you want a bulletproof one call up Winberg cranks in Denver. Pricy but worth it.

Probably a $6k rotating assembly but well worth the security of knowing you won't put a window in your block. :)

By chance do you have a link or part number for the Mahle piston?   I have searched but can't find anything.

I have a stock hellcat shortblock for my race car, the only thing I changed was th rod bolts. I put arps in them. The motor will make 1000-1200hp and I have no doubt the bottom end will hold together.

Does that include stock main bolts and caps?

Yessir, it sure does. The hellcat blocks have reinforced main webbing area and cuts down on the need for billet caps. I have no doubts the stock main bolts will hold just fine :)

Good deal.  I happen to have a new Hellcat block, and new Hellcat pistons and rings.  I am thinking use them with some molnar rods and crank and have a 377 short block ready for boost.

not as a drop in you would need the whole rotating assembly re balanced

Yep that's not a problem.  You have anything that would work?  Are the pistons worth using?

You can bet....there was a shit ton of research done on the hellcat piston. I would trust them as my as I trust my diamond billet pistons. I did however put arp rod bolts in my new hellcat shortblock

Carrillo will make you any set you want, if saving $350 on balancing is that big of a deal to you, they will definintly make you a set that will drop in with no balancing
