Alan, here is a pretty decent write-up. CLICK HERE (http://www.stangpro.com/html/articles/gt40p_files/gt40p1.htm). They claim .030 mill, would net about 10:1 compression ratio.

Al, I wouldn't mill them too much, I think they came stock with a 59 cc chamber....

many people I have talked to have said you can flat mill the "right set" up to .100''-.120''. The old street warrior guys did it all the time. I have done many sets at .030'' and .040'' and didin't have no problems.
