lunati flat top question

Can anyone tell me what the compression ratio is with a stock motor and the lunati nhra forged flat tops? It says 0cc dish but then it also says 10.8:1 comp on the specs in my SDPC catalog. Is this correct or is it stock 10:1 compression?

What cc heads do you have? That is a little high if you have stock LS1 heads. You will be down near 10:1.

Yep stock heads 67cc. Don`t know why the catalog said 10.8:1. Just want to make sure that the piston head isn`t thicker or somthing.

Did you see the pistons befor they went in?
If they were a true flattop you will have 10:1
The piston cant be any thicker without hitting the head or having a dome on it. So you probably have 10:1
