HELP !! Does anyone have access to a Cont. O-470
series parts book??-(or IO-470, or GO-470 )
I am considering using some 627738 pistons , but I need to know the compression ratio they produce.
( I do not have one or I could measure the dome & calculate it myself.) but they list the C.R.
with each different piston # in the parts book.
