| Post subject: | compression ratio |
I need some help here. I have a head milled .080, motor bored out .060 useing a stock head gasket can anyone tell me the compression ratio. Compcams has a cam I am thinking of useing but the catalog says it is designed for ratios of 9.1 or less. Also has anyone ever used a marine cam? A buddy of mine made that suggestion, he used to race circle track and said that the cam he used.  thanks for the help. OD |

If you "cc" the head and measure how far down in the hole the pistion is, we can figure the static CR. Without those measurments anything stated would be a "WAG". (my wild-a$$ guess is 8.8, do we hear 9...???) DD |

My "WAG" would be around 9.4-9.5  -S/6 |
