Comp. Ratio?

[4mulaSvaliant]

Anyone have access to the specs to figure out what the comp ratio may be on my 360 with 318 heads?
Both the motor and the heads are stock.
I know I know I am sufficating the 360, but when it was built it was on a High School budget. I have to say that combo is Torque-y as hell! Thats actually why Im wondering about the ratio.


Side note: Have J heads, need a new intake. Then it'll be a whole top end swap for some more HP. I love the torque this setup has now though, itll really be fun with the new suregrip back there!

the keith black website has a static compression ration calculator. of course you would need to know some measurments that you might not have. But you could proabably get them when you change your top end over and at least find out what ratio you will get.
