Horsepower increase
In a 351M, will boring the cylinders over, increase the compression ratio? If so, how much increase in horsepower can I expect, from the cylinders being bored .030 over, and what would .030 increase my compression ratio to?

Here.....answer your own question: Engine Size and Compression Calculator
As a very general rule of thumb, an increase in compression is worth about four percent more horsepower.
