Again, as I got it before it was not legal in a AB engine as the Hemi to do this.
I can’t understand why.
Keep posted.

About dome cc.
If you read the technical specifications its clear say dome cc ( max ) is 88.3 cc, and can’t be more if one like play it legal anyway.
But who’s going to check that in the barn, and this is coming from manufacture with credit to has a NHRA numbered piston.
So to get legal pistons done by manufactory whit correct data and numbered correct, it can’t be more cc on dome anyway.

I has never understand why the street Hemi never could had the std 425 rated HP as the 427 Chevy has it at the std HP.
That combo are equal to the Hemi in many ways but now way lighter, more comp, more cam, lighter rotating etc.
I know there has been racers using the street Hemi destroying this combo ( and HP on Monday but never been in tech after ) and it been over 450 and now 449 HP.
-I has never heard when it was rated std HP.
