Good news, I came across the part number doing research into building a more powerful duke thats not a super duty. I did find everything I was looking for at autozone. 9.0:1 CR standard size piston H547CP. Anyone looking to build a duke these pistons are what you want.

Isn't that lower than the stock duke CR?

That's the stock replacement part.
There is nothing desirable about that part for performance use. No increase in compression, not forged, not lighter weight, no gains.

It's a vague memory but I think maybe the earliest generation dukes were 8.5:1. The version used in Fieros is 9.0:1 though.

the duke is not a particularly good engine to soup up. the lower end has limitations in strength and the cylinder walls are not all that strong.

it has been tried numerous times, but for the cost of materials and time, it certainly will not satisfy in the long run

You will likely spend less and get more power out of an Ecotec swap.

I know this is an old thread, would there be enough valve clearance with flat pistons in a stock 2.5 duke? It would up the CR nicely.
