What is considered minimum for cylinder wall thickness on a 470 low deck stroker, no nitrious,
7.1" rod? I have a block that's betwen .133" & .153" on the minor thrust on #8 cycl. .157" on #2 minor thrust. .169" On #1 major thrust.
Rest of block is .188" to .259"




If you plan on making more than around 600 horse and its a dedicated race engine, id fill that block. You'll make more power too!
