My calculations says it's 12.99:1 using 7cc for valve reliefs (I'm not familiar with that piston).

[Jim Weise]

Rob,

Yes, if he has valve relief's in the piston, then you are correct. He did not spec out valve relief CC's or indicate that he does or does not have them, so I did not figure them in. With 7 cc of valve relief, that would cut about a point off of it.

Sorry, They do have valve reliefs
