I think are cars from the factory are some were around 8.1:1 CR. And I was woundering if any one now stocks good pistons to raise the compression ratio with out haveing to pay 600+ for custom pistions? What is a NA 3.8 compression ratio? I would love to try something around 9.1:1-9.5:1 forged or coated.
