Reply to "Seeking a Cam recommendation for a 393 with 4V heads"

The most important ratio is the dynamic ratio , not the static one. You must choose this ratio (George recommends not to exceed 8:1), then, depending on the angle of closing the inlet valve of the camshaft that you choose, you will deduce the static ratio and finally the amount to be milled on the cylinder head.

There are many Excel files that make it very easy to calculate all these values, if you want one ===> PM

All ways are not equal, there are some logics and others that are not.
