Flathead V8 Compression Ratios...6,020 choices

[21stud]

Chart has a typo about 41T head volume. I've measured those, came out around 82cc if my memory is correct.

Chamber shape is worth noticing though. It's much deeper at transfer area than any other Ford head but shorter towards piston. that is, similar to famous 81AS but real deep.

If someone would like to go milled and filled route to get real cheaters, these might be good for that?

Does anyone have the original excel file? Like many others I have saved the pdf, but would love to have the spreadsheet it was printed from.

Hi Fred,

You're welcome!

I've updated the spreadsheet, linking from and to the two instances for 41T heads within the preface and the column descriptions on sheets #8 and #10.
