i wanna go big bore and im wondering if yall would recommend just boring and plating the stock cylinder or buying aftermarket? also the piston isnt much higher in compression but, what is the weight diffrence in a stock 07 piston and the cp? what kind of increases am i looking at in terms of hp and tq? and last question is what does it normally run to bore and plate the cylinder? my other mods are in my sig.. thank you
