I imagine this topic has been beat to death over the internet, much in the same way it has for 460's, etc.

Looking to rebuild a factory 1975 Torino 351W. One of the things on the want list is of course a compression ratio increase - nothing crazy, just an increase to 9.0 to 1 or 9.5 to 1 (pump gas acceptable).

Since there were lots of heads and different configurations made over the years, choosing a precise piston is not that simple.

What I am looking for is some information sort of like the Bubba's M-block workshop stuff where all the data is listed and/or recommended pistons are listed to choose what I think I need. Since I am going to re-use the factory heads, etc I imagine the information is somewhere... I just don't know where that is!

Anyone know of a good resource to help me choose a piston to get 9-9.5 to 1 compression ratio?
