Making power out of the 318

I guess I should’ve specified that the motor is not assembled. The motor was not assembled when I bought it and that’s how I know one of the Pistons is cracked because the previous owner was taking it apart and dropped the stock piston so I can’t do any of that and that’s why I’m building the motor because my original plan was to get one that was already running and put that in and do a very mild build but since it’s already all apart, I might as well go for It. Thank you for the suggestion though.
Then I would choose a stock cast piston with the highest compression height. KB167 and forged this and that will just burn up more of your money unnecessarily. You're not building a race engine here, just something to have fun with.
