I bought a 01 cobra motor for my gt and I was wondering if the compression ratio for the pistons is that same as the 03 and 04 supercharged cobras. If you know the comp ratios that would be great. Also how much boost can your run on those motors, I ran 8psi on my 4.6 sohc and thats about max on those. I'de like to know so I don't blow this motor like I blew my gt motor....
