compression on a 360

the pistons in my 360 are .040 that are factory styled dish.. they measured about .070 or so in the hole.. don't know what brand they are... So if calc's are correct and i use a -10.00cc dish with the .040 compressed thickness of my headgaskets... It says my compression is about 8.66:1.. assuming that the dish is 10.00..that is also using a 66cc chamber.. If teh chamber is 62cc then it's 8.98:1 according to calc's (but i doubt that's the case.)




I guess we'll see.. new pistons are goin in eventually.. kb107's or something after I get the car together. 8)
