Question Stock compression ratio ?

Hey guys, I was wondering what the stock compression ratios are for my 300 I6. I have looked and all I found nothing.

I know 8.5 pistons were available as I put those in mine when I rebuilt it the second time.

Probably either 8.3 or 8.7:1. Check on www.kb-silvolite.com under 4.9- they give compression ratios there.
