So I am rebuilding the raptor. With that said, I have it all apart right now and the stock piston that is in it looks just fine. I was wondering.. If I decide to buy a forged piston..lets say a weisco 11:1..Will running the high compression piston in the stock cylinder, stock bore size make any difference power wise? Whereas if I were to have the cylinder bored .30 to make it a 686 and run the weisco .30over piston? What does cylinder boring cost, and what does it entail? I didnt know if I would get any power difference at all running a high comp piston in the stock bore size.. Id hate to put the stock piston back in it but it looks clean and is here right now and dont have to invest anymore money..
