68 440 block .030 over
had it machined in 1988 or so (when I was young and dumb), and purchased the common forged flat tops (2266?)
over the years, I became aware of bogus compression ratios, and the "down in the hole" issue (appears to be .090-.010ish)..... so at some point, being the know-it-all that I am; I rounded up a set of 915 heads (big ex valves, hardened seats installed).
had the 915s cut, did the math, and came up with 9.6ish CR, IIRC
looking back, I probably should have done things differently, but my question is (now that I am old and dumb)........ will this POS run without dropping back and punting?
