Alot of the parts we had was already sitting around. As it stands, the KA is the only option. There's no option of another engine. That means more $$$ that we can't afford to dish out. I wanted to know if anyone had heard of installing the SOHC pistons into the DOHC block and if so, how much compression would it take it to. I'm about a mouse button away from buying the SOHC pistons if the comp isn't too high. We're already ordered stage 2 cams, the block is fully dissasembled. It's about to go to the machine shop as soon as we order pistons for it. It's gonna be bored .020 over. So does anyone know anything about it? Thanks for your opinions.
