Pat,
I heard the new 496HO's come with Forged pistons. Am I wrong???

Re: 525 vs. 496 HO--supercharged
 

Hi Rick,
Sorry, but yes you are wrong. All the GM 496cube/8.1L engines come through stock with cast pistons, even the 525HP HP3.
There are aftermarket kits with forged pistons available now though.

Re: 525 vs. 496 HO--supercharged
 

It's my understanding that some of the very first 496 HOs came with forged internals.

Crank yes pistons no...
