This is especially for Bill O'!!
I've seen on the Net several pics of ported crankcases......
my question is: is this mod useful on a stock displacement engine also with canonic mods? (cyl. porting, perf. exhaust, etc....) My idea is that the porting increases and also redirect the incoming flow but also normally increases the volume of the crankcase that was carefully studied by builders of it. A bigger crankcase means logically a lower primary compression ratio that could be negative on a stock displacement engine, things naturally change on big bore or stroker engines where the displacement is increased and normally porting the crankcase becomes mandatory.
Any idea or advice is welcome!!
Thank you Michele
