I thought I read somewhere that the 75 pistons 95mm. So would it be worth it to but a set of 75 pistons and have my 74 bored? I need to do a little more research about the math that goes into the compression ratio. I know there's a thread about the the cr with a 74 bottom and 75 heads, but I don't remember if I saw it here, on galanttuners, or club3g. It's all running together lol
