    How can you figure out how many cc's your motor is?

    Was talking to a friend of mine about the engine in our 99. He wanted to know how many cc's it is now with 5mm stroker build in it. I actually dont know but was wondering how can i figure it out?

    displacement formula= 0.001*2*stroke*3.1415927*(bore/2)^2

    64U really had 1131cc

    If your bore is 84mm and your rod is 73mm (factory is 68mm I believe) then you have 1214cc

    cool thanks so when i eventually freshen up this motor in probably two years or so i could punch the sleves out to 89mm (largest you can go i think) and the motor would be 1362cc then right?
