Ok i have searched and I understand that the D17 blows hard core. Just wondering though if the Y8 head would mount up to the D17 block? If so has anyone done this? Im looking to see what items were neded to make it happen like T belt and crap. What is the bore on D17's. I wanna see if maybe get a 1/2 assed stroked Sohc vtec mini me going on. Plz dont flame me for asking Im just curious.
